Turkey's involvement in theSyrian civil war began diplomatically and later escalated militarily. After a decade of relatively friendly relations with Syria from 2000 to 2010, Turkey condemned Syrian presidentBashar al-Assad over theviolent crackdown on protests in 2011 and, from the beginning of the war, Turkey trained defectors of theSyrian Army in its territory under the supervision of the TurkishNational Intelligence Organization (MİT), among whom emerged theFree Syrian Army (FSA) in July 2011. The Turkish government's involvement further evolved intoborder clashes in 2012, and direct military interventions in 2016–17,2018,2019,2020, and2022, resulting in theTurkish occupation of northern Syria since August 2016. In December 2024, Turkish proxy forces involved in the 2024 Syrian rebel offensive toppled the Assad regime in Damascus with U.S. support, turning into the most influential party during the conflict.
Until 2016, Turkey had addressed the Syrian civil war by using more diplomatic means such as through international diplomacy and targeted sanctions. Tensions between Syria and Turkey significantly worsened after Syrian forcesshot down a Turkish fighter jet in June 2012, and border clashes erupted in October 2012. On 24 August 2016, the Turkish Armed Forces began a direct military intervention into Syria by declaringOperation Euphrates Shield, mainly targeting theIslamic State of Iraq and the Levant. It had also fulfilled other pre-existing Turkish policy goals, such as limiting the influx of therefugees of the Syrian civil war.
Turkey has historically strongly supported Syrian dissidents, as it became increasingly hostile to the Assad government's policies and encouraged reconciliation among dissident factions. Turkey financed theNational Coalition of Syrian Revolutionary and Opposition Forces, also known as the Syrian National Coalition, and facilitated the establishment of theSyrian National Army.
Turkey and Syria have a history of tense relationships. According to Turkish officials, between 1957 and 1998, Turkish forces laid 615,419 antipersonnel mines along the Syrian border "to prevent illegal border crossings." Under theMine Ban Treaty, Turkey is required to destroy the mines, but has missed deadlines. AHuman Rights Watch (HRW) report states that as of 18 November 2014, over 2,000 civilians were still in theTall Shair corridor section of the mine belt since Turkey had been refusing entry for cars or livestock, and the refugees did not want to leave behind their belongings.[140]
In 1957, Turkey threatened Syria with war if it allowed Russian military to build bases there, which led to theSyrian Crisis of 1957. Later, in the 1980s and 1990s, the two governments could not agree on sharing theEuphrates andTigris rivers, with Syria and Iraq criticizing Turkish dam projects on these rivers in Anatolia. In addition, the Syrian government used to support theKurdistan Workers' Party (PKK) and its affiliated groups, preferring to use the Kurdish issue as a trump card in its relations with Turkey, particularly in the 1990s,[141] and later in 2011, when it withdrew from parts of Northern Syria and gave them to the PKK-affiliatedPeople's Protection Units (YPG) rather than letting it fall into the hands of Syrian opposition.[142]
Turkey and Syria had a rather strong bond in the 2000s,[143] due to lax migration laws between the two countries.[144][145] Since theJustice and Development Party (AKP) was chosen as the ruling party in Turkey in 2002, it took a new direction in its policy in Middle Eastern relations, leading to bilateral relations between Syria and Turkey improving.[146] The normalization of relations started in late 2004, when Erdoğan, then Prime Minister of Turkey, flew to Damascus to sign afree trade agreement.[147] This more liberal approach towards neighboring countries includedopen border policies with Syria, and more dialogue on cultural and civil-society levels.[146]
After the outbreak of the Syrian civil war in 2011, the Turkish government condemned the actions of the Syrian government.[148] Furthermore,Syrian opposition activists convened in Istanbul in May 2011 to discuss regime change,[149] and Turkey hosted the head of the Free Syrian Army, ColonelRiad al-Asaad.[150]
On 22 June 2012, a TurkishMcDonnell Douglas RF-4E Phantom II reconnaissance jet wasintercepted andshot down by the Syrian Army in international airspace, greatly escalating tensions between the two countries.[151][152] In October 2012, numerousclashes took place along theSyrian–Turkish border,[153] strainingbilateral relations and resulting in dozens of civilians and military personnel killed. Syria has repeatedly urged the UN Security Council to "put an end to the crimes of the Turkish regime."[154]
Turkey has accepted over 3.5 millionSyrian refugees since the beginning of theSyrian civil war.[155] Turkey has accommodated most of its Syrian refugees in tent cities administered by the country's emergency management agency.[156] The population of Syrian refugees in Turkey is 30 percent in 22 government-run camps near the Syrian-Turkish border.[157]
Satellite images confirmed that the first Syrian camps appeared in Turkey in July 2011, shortly after the towns ofDeraa,Homs andHama were besieged.[158] By June 2013, Turkey had accepted 400,000 Syrian refugees, half of whom are spread around a dozen camps placed under the direct authority of the Turkish Government.[156] In 2014, the number swelled to over a million, as some 200–300,000 Syrian Kurds streamed into Turkey in September alone, upon theSiege of Kobane.[159]
Erdoğan stated that Turkey was ready to resettle the Syrian refugees in the northern area that Turkey had invaded in October 2019, and that Turkey would pay for it if necessary.[160] On 9 December 2019, various local accounts indicated that Turkey was moving Syrian refugees into its zone of operations in Northern Syria for the first time;[161] one million people were planned to relocate to the cities ofTell Abyad andRas al-Ayn in particular.[162] This has led to fears of population change.[163]
Since mid-January 2016, Turkey has forcibly returned thousands of Syrian refugees to war zone.[164][165][166] On 10 May 2016, a video by HRW showed Turkish border guards shooting and beating Syrian refugees trying to reach Turkey, resulting in deaths and serious injuries, but Erdoğan and a Turkish official denied the authenticity of the video.[167][168] On 18 May 2016, lawmakers from theEuropean Parliament Subcommittee on Human Rights said that Turkey should not use Syrian refugees as a bribe for the process of visa liberalization for Turkish citizens inside theEuropean Union.[169]
At the beginning of the Syrian Civil War, Turkey trained defectors of theSyrian Army, a number of whom announced the birth of theFree Syrian Army (FSA), under the supervision of theNational Intelligence Organization (MİT), in July 2011.[174] In October 2011, Turkey began sheltering the FSA, offering the group a safe zone and a base of operations. Together withSaudi Arabia and Qatar, Turkey has also provided the rebels with arms and other military equipment. Turkey's geo-political maneuvering, according to scholars such as Ataman and Ozdemir, is in line with its larger ambition to limit the influence of Iran on the region.[175]
Turkey, Qatar, and Saudi Arabia have supported theArmy of Conquest.[176] The coalition includedal-Nusra Front andAhrar al-Sham, which were linked to al-Qaeda, as well as other Islamist factions such as theSham Legion, which received covert arms support from the United States.[177] According toThe Independent, some Turkish officials said they were giving logistical and intelligence support to the command center of the coalition, but said they did not give direct help to al-Nusra Front, while acknowledging that the group would be beneficiaries. It was also reported by some rebels and officials that Saudis had given monetary support and weapons to Islamist groups, with Turkey facilitating their passage.[178]Al-Ahram reported that U.S. President Obama chose not to confront Saudi Arabia and Qatar over the issue at a May 2015 meeting of theGulf Cooperation Council, although al-Nusra Front and Ahrar al-Sham troops made up 90% of the troops in theIdlib region, where they were making substantial gains against the Assad government.[179]
In 2013, Turkey had reportedly criticized the timing of the designation of al-Nusra Front as a terrorist organization,[180] butAl-Monitor said in 2013 that Turkey was reconsidering its support for al-Nusra. In June 2014, Turkey began classifying al-Nusra Front as a terrorist group, a decision that was seen as them giving up on the group.[181][182] In June 2014,İhsan Özkes, a parliamentarian from theRepublican People's Party, stated that a directive had been signed by Turkish Interior MinisterMuammer Güler, ordering the provision of support to al-Nusra against theDemocratic Union Party (PYD), but Güler said that a directive with the letterhead of the Governor's Office of Hatay could not be possibly signed by a minister, which is direct proof of the document's inauthenticity.[183][184]Francis Ricciardone, formerUnited States Ambassador to Turkey, stated that Turkey had directly supported and worked withAhrar al-Sham and al-Qaeda's wing in Syria for a period of time thinking that they could work with extremist Islamist groups and push them to become more moderate at the same time, an attempt which failed. He said that he tried to persuade the Turkish government to close its borders to the groups, but to no avail.[185]Seymour Hersh, in an article published onLondon Review of Books on 17 April 2014, said that senior US military leaders and the intelligence community were concerned about Turkey's role and stated that Erdoğan was a supporter of al-Nusra Front and other Islamist rebel groups.[186]
Arab media stated that the village ofZanbaqi inJisr ash-Shughur's countryside has become a base for a massive amount ofUyghur Turkistan Islamic Party militants and their families in Syria, estimated at 3,500. They further stated the MİT was being involved in transporting these Uyghurs via Turkey to Syria, with the aim of using them first in Syria to helpal-Nusra Front and gain combat experience fighting against the Syrian Army before sending them back toXinjiang to fight against China if they manage to survive.[190][191] Arab news agencies reported that the Uyghurs in the Turkistan Islamic Party, the Chechens inJunud al-Sham, al-Nusra Front and Ahrar al-Sham were coordinated by Turkish intelligence to work with the Army of Conquest.[192] Turkish media agencies, on the other hand, denied this and stated that it was a scheme by the Chinese government to promise a holy cause and new lands to Uyghur forces with Islamic tendencies, which would eventually be cited by the government as the reason for more oppressive policies towards the Uyghur people.[193] The validity of the Chinese statements had also been challenged by Sean Roberts of Georgetown University in an article on global terrorism.[194] Conversely, other reports emphasized the Uyghur fighters' ties with ISIL, which led to the2017 Istanbul nightclub shooting against Turkey.[195]
On 3 February 2020, Syrian and Turkish forces exchanged fire inIdlib, Latakia and the northern Aleppo countryside during the5th northwestern Syria offensive. Turkey and the SOHR reported that seven Turkish soldiers, one civilian contractor, and 13 Syrian soldiers were killed.[196][197] Turkey's president Erdoğan demanded that Russian forces in Idlib "stand aside"; he nevertheless dismissed the possibility of direct conflict with Russia saying Turkey and Russia would talk about the issue "without anger".[198] On 10 February, Syrian government forces shelled a then-recently built Turkish observation post atTaftanaz Military Airbase, killing six Turkish soldiers and four Syrian rebels, according to the SOHR.[199] On 11 February, Turkish Armed Forces shot down a Syrian Government helicopter,Mil Mi-17, nearNayrab, killing all its crew.[200][201] On 27 February, 33 Turkish soldiers were killed in theBalyun airstrikes carried out by theSyrian Air Force.[202] Therefore, Turkey and proxy forces started to target the regime forces and their allies until they recapturedSaraqib, and cut the Damascus-Aleppo M5 highway once again.[203] The deadline to withdraw to the initial de-escalation lines behind the Turkish observation points, previously set by Erdoğan to halt the Syrian regime assault in Idlib Governorate, ended by the end of February.[204]
On 1 March, Turkey initiated a military operation code-namedOperation Spring Shield (Turkish:Bahar Kalkanı Harekâtı) against the Syrian regime, which aimed to protect local Syrians and to install a lasting ceasefire, according to Turkish Defense MinisterHulusi Akar.[205] From 27 February to 5 March, Turkey claimed the Turkish military neutralized 3,138 Syrian Army soldiers and militia, and destroyed the following material: 3 fighter jets, 8 helicopters, 3 UAVs, 151 tanks, 47 howitzers, 52 launchers, 12 antitank weapons, 4 mortars, 10 arsenal depots and 145 military, technical and combat vehicles.[206] TheTurkish Armed Forces have also released 12 minutes of drone footage that wrought havoc. According to the SOHR, Turkish troops killed 165 Syrian soldiers and fighters loyal to the regime.[115] On 5 March, Turkey and Russia announced that a ceasefire in Idlib would come into force on midnight, a decision taken in light of the rising number ofhuman rights violations since the offensive began in the region. Despite the two countries reaching an agreement, Turkey said that it still held "the right to retaliate with all its strength" against future attacks carried out by the forces of theSyrian government.[207]
Turkish Army artillery bombard a SDF position in the northern Aleppo countryside in July 2017
The Turkish government promotes the narrative that the Syrian KurdishDemocratic Union Party (PYD), the leading political party of theAutonomous Administration of North and East Syria, and the YPG militia, the leading component group of theSyrian Democratic Forces (SDF), were reportedly taking control of andethnically cleansing land which did not belong to the Kurds. No evidence has been provided for these assertions, which were refuted by theUnited Nations.[208][209][210][211] Turkish president Erdoğan has stated that Arabs would be more able to live in the area, which he believed was mostly desert, althoughSyrian Kurdistan is mostly north of theSyrian Desert.[212][213][214][215] Political analysts stated that throughout the Syrian civil war, while Turkey presented itself as the protector ofSyrian Turkmens, its real goal was to fight Kurdish forces, as Turkey ignored several atrocities committed by the Syrian government against Turkmens during the war.[216]
Turkey has received the co-chair of the PYD,Salih Muslim, for talks in 2013[217] and in 2014,[218] and entertained the idea of opening a Rojava representation office inAnkara if it abides by the city's policies.[219] Opposition leaderSelahattin Demirtas has suggested for Turkey and other countries to recognize Rojava and work with it as a partner,[220][221] but Turkey remained persistently hostile because it feels threatened by Rojava's emergence encouraging activism for autonomy amongKurds in Turkey and theKurdish–Turkish conflict, and in this context in particular Rojava's leadingPYD and the YPG militia being members of theKurdistan Communities Union, which also includes both political and militant Kurdish organizations in Turkey itself, including the PKK. Turkey's policy towards Rojava is based on an economic blockade,[222] persistent attempts of international isolation,[223] opposition to the cooperation of the international Anti-ISIL-coalition with Rojava militias,[224] and support ofIslamist Syrian Civil War parties hostile towards Rojava,[225][226] in past times including ISIL.[227][228][229] On several occasions, Turkey has also been militarily attacking Rojava territory and defence forces.[230][231][232] The latter has resulted in some of the most clearcut instances of international solidarity with Rojava.[233][234][235]
A vote in theTurkish Parliament was scheduled for 1 October 2014 on whether or not to invade Syria as part of the war on ISIL[236] while preparations for a possible intervention were made.[237] It was later delayed a day.[citation needed] Thede facto "declaration of war" took the form of two separate motions, one on Iraq and one on Syria, which would authorize Turkish troops to invade those countries.[238] Deputy Prime Minister Bülent Arınç said that the gist of the resolutions was to extend the current mandate for "hot pursuit" against the PKK and Syrian Army into Syria and Iraq, which was to end the second week in October, to add the Islamic State to the list, and to set up a buffer zone on the Syrian side of the border.[239]
President Erdoğan opened the parliamentary session by saying that Turkey would fight against the Islamic State and other "terrorist" groups in the region, but would stick to its aim of seeingBashar al-Assad removed from power.[240] After two days of heated debate, the motion passed 298–98.[241]
With the Turkish government believing that a declaration was enough, and with only a minimum of western airstrikes helping the defenders ofKobanî, ISIL troops edged closer to the city, eventually entering it from the southwest.[242] Feeling betrayed by the Turkish government and hearing that Prime MinisterAhmet Davutoğlu's previous vow not to let Kobanî fall was actually a lie, refugees on the border and Turkish citizens began to protest. Turkish police responded with tear gas and water cannons, and live ammunition in the southern province ofAdana, killing protestors.[243]
By 7 October, ISIL militants and Kurdish defenders were fighting in the streets of Kobanî, with many dead and scores wounded on both sides.[244][245] Meanwhile, rioting continued in Turkey, and 31 people were killed in street clashes by mid-October.[246] In late October, ISIL began shelling the border post near Kobanî.[247] On 11 October, Turkish President Erdoğan denounced the protests, stating that they were attacking Turkey's "peace, stability, and environment of trust." He stated that the government was already caring for 200,000 Kurdish refugees from the Kobanî area and asked, "What does Kobanî have to do with Turkey?"[248] By mid-October,fighting had also renewed between Turkish military forces and PKK elements in southeastern Turkey.[249]
On 29 November 2014, ISIL began attacking the YPG in Kobanî from Turkish territory.[250] During the attack, a group of ISIL fighters were seen atop granary silos on the Turkish side of the border.[251][252] According toDer Spiegel, ISIL fighters also attacked YPG positions near the border gate from Turkish soil.[253] According to the SOHR, YPG fighters crossed the Turkish border and attacked ISIL positions on Turkish soil, before pulling back to Syria. Soon afterward, the Turkish Army regained control of the border crossing and the silos.[254]
On 25 June 2015, fighters fromISIL launched anattack against Kobanî, detonating threecar bombs.[255] The ISIL fighters were reported to have disguised themselves as Kurdish security forces, before entering the town and shooting civilians with assault rifles and RPGs.[256][257] Over 164 people were killed and 200 injured.[256] Kurdish forces and the Syrian government stated the vehicles had entered the city from across the border, an action denied by Turkey.[258] ISIS also committed a massacre in the village of Barkh Butan, about 20 kilometres south of Kobanî, executing at least 23 Syrian Kurds, among them women and children.[259]
With the governing party losing its majority in theTurkish general election on 7 June 2015, rumors began to circulate thatPresident Erdoğan would order an intervention of Syria to prevent the creation of a Kurdish state straddling northern Syria and Iraq.[260] Leaked plans stated that, sometime during the first couple of weeks of July, up to 18,000 troops would invade Syria via theJarabulus andAzaz borders, which were in the hands of ISIL and the Free Syrian Army, respectively, and set up a buffer zone to which refugees could be repatriated.[261] Limiting intervention to airstrikes has also been discussed,[262] since the idea of invading Syria proved extremely unpopular with most sections of Turkish society.[263]
By the end of June, a number of Turkish newspapers reported that Ankara was considering a ground operation to establish a buffer zone in Northern Syria to prevent Syrian Kurds from declaring an independent state, a zone 110 km long and 33 km deep along the Turkish border.[264] The military demanded legal backing for such a move,[265][266] which Erdoğan provided on 29 June by chairing a meeting of the National Security Council.[267]
2015–2016: Rojava expands and increased Turkish hostility
On 24 and 25 October 2015, Kurds said the Turkish military opened fire at its forces inTell Abyad after the majority Arab town was included intoKobanî Canton. Davutoğlu confirmed it, saying "we hit it twice".[268][269] There were no casualties in the shooting and the Kurdish forces did not return fire.[270] On 25 October, Turkish forces also attacked the village of Buban, wounding two civilians during the attack.[271]
In addition, SOHR said that Turkish troops were shelling the road to the west ofTal Rifaat and the region to the west of the Syrian border town of Azaz, but failed to stop the advance of the Kurdish forces.[272] On 16 February 2016, Turkish forces continued to shell the positions of Syrian Kurds in northern Syria for the fourth day. Turkish military said that it was retaliating to fire coming from the region.[273] On 17 February 2016, in Ankara, acar bombing attack happened at night. The attack targeted a convoy of military vehicles. Davutoğlu and President Erdoğan blamed a Syrian Kurdish militia fighter working with Kurdish militants inside Turkey for a suicide car bombing, and vowed retaliation in both Syria and Iraq.[274] However theKurdistan Freedom Falcons took responsibility for the attack and said they targeted security forces.[275]
In February 2016, Turkey and Saudi Arabia were pressing for ground operations in Syria, hoping for the involvement of the U.S. and other allies.[276] Hezbollah said Turkey and Saudi Arabia were using the Islamic State group as a "pretext" to launch a ground operation in Syria.[277] On 17 February 2016, Erdoğan said that Turkey would continue shelling Kurdish militants across the border in Syria, despite calls from Washington and other Western capitals to halt the attacks.[278] Opposition groups reported that over the previous few days they had brought over 2,000 reinforcements with heavy equipment from the Idlib area, through Turkey assisted by Turkish forces, to fight against Kurdish militias north of Aleppo and to support rebels in Azaz.[279]Pentagon Press Secretary Peter Cook said that Turkey's shelling of YPG forces in northern Syria would be an "ongoing topic of conversation" between the United States and Turkey.[280]
On 22 February 2016, a U.S.–Russia joint cease-fire deal was announced to take effect in Syria on 27 February, but it did not include ISIL and al-Nusra Front, the main jihadist factions. During a speech on 24 February, Erdoğan said that "the PYD and the YPG need to be out of the scope of the cease-fire, just like Daesh (ISIL) is".[280] On 4 March 2016, the YPG militia said that Turkey's tanks had fired dozens of shells at its positions in the area ofAfrin in northwest Syria.[281] On 8 March, mortar shells fired from Syria in Turkey, killing two civilians and prompting the Turkish military to return fire into Syria. According to Davutoğlu, Islamic State militants were responsible for the attack.[279]
In the wake of the major military advances that Syrian government forces andSyrian Democratic Forces made against jihadists during theNorthern Aleppo offensive, Ankara called for a safe zone andno-fly zone in northernAleppo governorate.[282] The proposal did not garner any real support from Washington orNATO allies, who feared it would require an internationally patrolled no-fly zone and potentially put them in direct confrontation with Assad and his allies. German ChancellorAngela Merkel said that such a safe zone would be helpful, but Russia, who held dominance over Syria's skies, opposed the idea; Russian Foreign MinisterSergey Lavrov clarified that "this is not Merkel's initiative, this is a Turkish initiative." In addition, Russian Deputy Foreign Minister Gennady Gatilov said that any decision to create a no-fly zone over Syria cannot be made without the approval of the government in Damascus as well as the UN Security Council.[282]
In April 2016, factions of the SDF formed theManbij Military Council.[283][284] The U.S. asked for Turkey's support for the Manbij offensive, but Turkey had two demands that were rejected, namely that the forces in the offensive should leave thesecular SDF umbrella, and that the U.S. should increase its airstrikes for jihadist groups Turkey supports.[285][286][287] When the offensive started, theWashington Post reported it under the headline of "Ignoring Turkey, U.S. backs Kurds in drive against ISIS in Syria".[288]
On 24 August 2016, the Turkish armed forces, backed by planes from a U.S.-led coalition, began their first direct military intervention into Syria, calledOperation Euphrates Shield.[289] After two days of artillery bombardment and airstrikes,[290] theTurkish Land Forces launched an attack on the ISIL-held town ofJarabulus, followed by hundreds of FSA fighters.[291] It was the first time Turkish warplanes have struck in Syria since November 2015, when Turkey downed a Russian warplane, and the first significant incursion by Turkish special forces since a brief operation to relocate thetomb of Suleyman Shah in February 2015.[289]
The immediate goal of the military intervention was the capture of Jarabulus, which was accomplished on the first day of the operation,[289] but the intervention escalated into theTurkish occupation of Northern Syria.[292] Turkey said the operation was an act of self-defence, in response to ISIS shelling Turkish border towns and suicide bombings and attacks targeting Turkish nationals.[289] Erdoğan said on the first day of the operation that it was aimed against both the ISIL and the YPG, a major component of the SDF, saying both "terror groups [...] threaten our country in northern Syria".[293][294] Turkish foreign ministerMevlüt Çavuşoğlu added that the YPG should return east of Syria's Euphrates River, since bothManbij and Jarabulus are west of the river.[290] Syrian Kurdish forces said that the Turkish operation was motivated more by the desire to stop their advance at Jarablus than by anti-ISIS sentiment.[295]
The SDF managed to take the town of Amarinah from the FSA after a brief firefight.[289][296][297]U.S. Special Operations Forces embedded with the SDF to successfully deter Turkey and Turkish-backed jihadi rebels from attacking SDF forces south of the Sajur river in Manbij;[234] on 20 September 2016, theUnited States Department of Defense added that Special Forces were flying American flags in the town ofTell Abyad inKobanî Canton to further deter Turkish attacks.[298][299] On 21 September,The New York Times reported that the U.S. administration "is weighing a military plan to directly arm Syrian Kurdish fighters combating the Islamic State, a major policy shift that could speed up the offensive against the terrorist group but also sharply escalate tensions between Turkey and the United States."[300] Reacting to these reports, Erdoğan said on 23 September that "arming another terrorist group for fighting another terrorist group is not acceptable."[301] Following these statements, the Turkish army shelled two YPG positions in the Tell Abyad area.[302] On 25 September 2016, the U.S. spokesman for theCombined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) confirmed that the SDF, including the YPG, were also part of the "vetted forces" in thetrain-and-equip program and would be supplied with weapons. Erdoğan condemned this and said that the SDF were "endangering our future".[303]
On 26 September, Turkey's Deputy Prime MinisterNuman Kurtulmuş welcomed the withdrawal of some YPG units east of the Euphrates river.[304] On 27 September, Turkey sent military units to the border area ofAkçakale.[305] The same day, Çavuşoğlu said that YPG units had not withdrawn from Manbij and its countryside and stated "this means USA either is not capable of influencing YPG or they do not want to influence them."[306] On 3 October, the Turkish government once again stated that fighters of YPG were still present west of the Euphrates and called on the U.S. to hold to its promise that they withdraw to the east of the river.[307] The following day, Yıldırım said that Turkey could use force to expel YPG from Manbij.[308] Due to the continuing Turkish threats, on 4 October, the SDF spokesman explicitly ruled out any Turkish participation in theupcoming joint military operation of the SDF and the CJTF–OIR to captureRaqqa from ISIL.[309] Later an Obama administration official said that the administration's "Plan B" to retake Raqqa by arming the Kurds was adopted after the initial plan of using Turkish forces in the Raqqa offensive became unattainable.[310]
Turkish military vehicles on the Syria–Turkey border, 16 January 2018.
On 18 October 2016, Erdoğan said that the YPG would be removed from Manbij after ISIL was driven fromal-Bab.[311] On 25 October, Çavuşoğlu stated that Turkey would dislodge "PYD/PKK" from Manbij if it did not leave the city,[312] a sentiment expressed by Erdoğan the following day.[313][314] On 11 November, Erdoğan stated the Turkish intervention intended to expand the area under the FSA's control to 5,000 square kilometres (1,900 sq mi), which includes al-Bab, Manbij and Tell Rifaat, allowing Syrian refugees to return to the respective cities with help from the European Union, and he would focus on Raqqa and the PYD afterwards.[315]
On 29 November, Erdoğan said that the Turkish military launched its operations in Syria to end the rule of Syrian President Bashar al-Assad.[316] Days later, Erdoğan sought to retract his statement; media observers attributed his outburst to frustration due to failure of his government's Syria policies.[317]
Acting U.S. Assistant Secretary of Defense for International Security Affairs,Elissa Slotkin, said on 16 January 2017 that the only target for the US-led coalition is ISIL, and not the city of Manbij that had been cleared from ISIL by the SDF. "We are all about hitting ISIS where there is ISIS. If there's no ISIS, that's not our mandate. So that is an important distinction. We have always made it in any kind of conversation we've been having with any ally on Syria."[318] On 20 January 2017, the Deputy Prime Minister of Turkey, Mehmet Şimşek, said that "we can't say that Assad must go anymore. A deal without Assad isn't realistic."[319] On 27 January 2017, after themultilateral peace talks in Astana, Erdoğan said that "we should not go deeper than Al-Bab" and Çavuşoğlu said "there are different opinions about YPG and Hezbollah. So an agreement can not be reached about the struggle against them".[320] On 31 January, the Germany Defence Ministry ruled out giving Turkey unfiltered access to high-resolution aerial imagery gathered by Tornado fighter jets operating out ofIncirlik Air Base in southern Turkey as part of the anti-ISIL coalition, out of concern that Turkey might use it for military action against the SDF.[321]
On 1 November 2016, the day Iraqi forces entered Mosul in theBattle of Mosul (2016–17) against ISIL, Turkey announced it was sending tanks and artillery from Ankara toSilopi near the Iraqi border. Turkey's Minister of DefenseFikri Işık said the deployment was a move to "prepare for "important developments" in the region and stated that "further action can be taken if Turkey's red lines are crossed".[323][324][325] Iraqi Prime Minister Al-Abadi, while addressing journalists in Baghdad, warned Turkey not to invade Iraq, predicting war if they did.[326]
On 5 April 2017, President Recep Tayyip Erdoğan suggested that future stages of the – recently proclaimed concluded – Euphrates Shield Operation would be broader, suggesting that Turkey would also seek to occupy territory of Iraq. Erdoğan said that "a future operation will have not [only] a Syrian dimension, [but] also an Iraqi dimension. There are theTal Afar andSinjar situations [in Iraq] We also have kin inMosul."[327]
In January 2018, the Turkish military began an intervention in the Afrin region of Syria, code-named by Turkey as Operation Olive Branch (Turkish:Zeytin Dalı Harekâtı). TheTurkish Armed Forces announced the start of the Operation on 20 January,[328] while the Turkish Defence Minister said it started with cross-border shelling the day before.[329] This followed Erdoğan's parliamentary address to his ruling AKP on 9 January, in which he said that Turkey will continue its military operation in Syria'sAfrin and Manbij regions.[330]
On 28 October 2018, following a summit with the heads of state of France, Germany, Russia and Turkey,[331] Turkey started shelling targets in northern Syria.[332] On 12 December, Erdoğan said during a televised speech that Turkey would launch a military operation against the Kurds east of the Euphrates river in northern Syria within days. He added that since the US-backed Kurdish fighters in Syria had not left the town of Manbij and the Americans would not remove them, as agreed in a US-Turkish deal, that Turkey would do it.[333] The United States responded that such actions would be unacceptable and that "coordination and consultation between the U.S. and Turkey is the only approach to address issues of security concern in this area."[334] Erdoğan also said that Turkey's "anti-terror" operations in northern Iraq would continue.[335]
Following the January2019 Manbij bombing, Erdoğan told Trump that Turkey was ready to take over security in the town.[336] In October,another Turkish offensive into north-eastern Syria began, after US President Trump ordered the withdrawal of US forces. According to Erdoğan, the operation was intended to expel the SDF from the border region as well as to create a 30 km-deep (20 mi) "safe zone" in Northern Syria where some of the 3.6 millionSyrian refugees in Turkey would resettle.[337] This intention was criticized as an attempt atethnic cleansing,[338][339][340][341][342][343] a criticism denied by the Turkish government, who said they intended to "correct" the demographics that they alleged have been changed by the SDF.[343] Turkey began to appoint mayors in several northern Syrian towns in late 2019.[344]
A journalist team from CNN consisting of correspondent Clarissa Ward, producer Salma Abdelaziz and cinematographer Christopher Jackson filmed exclusively as civilians fled the offensive from the town ofRas al-Ayn, Syria.[345] CNN received an Emmy award for Outstanding Breaking News Coverage for their reporting.[346]
The prospects for Kurdish autonomy in the region severely diminished, because the Kurds were exposed to the Turkish-led offensive by the U.S. withdrawal and the Russia-backed Syrian government forces under Assad—whose commonality is enmity towards Turkey and Sunni rebel militias—regaining their foothold in northeast Syria after the Kurds had to seek their help.[347][348] In December 2019, various Kurdish factions that were historical rivals began to meet in order to work together more. Their stated reason was to stand together against Russia and Turkey if needed.[349][350] The Russian government has informed the Kurdish factions that they should reconcile and come up with a unified set of demands to clarify to Russia.[351] Various Kurdish factions blamed each other and their council for lack of progress.[352]
Following European criticism of the2019 Turkish offensive into north-eastern Syria, Erdoğan threatened to open the borders for migrants to Europe,[353] and to expel foreign jihadists in its custody.[354] In June 2020, the Syria's permanent representative to the UN accused the US and Turkey of having deliberately set fire to agrarian crops at theJazira Region in Syria.[355] In March 2023, thousands protested at the town ofJindires against the Turkish-backed armed groups controlling the area, after the killing of four Kurdish men who were celebratingNowruz. Jaish al-Sharqiya, a splinter group ofAhrar al-Sharqiya accused for the murders of the Kurdish men.[356]
On 26 November 2022, SDF commander-in-chiefMazloum Abdi stated that they halted operations against the Islamic State group due to Turkish attacks on northern Syria. He also accused Turkish strikes of causing severe damage to the region's infrastructure. Two rockets also targeted U.S.-led coalition forces at bases in the northeastern Syrian town ofAsh Shaddadi.[357] According to SOHR, Turkish forces killed 138 Kurdish and SDF-fighters, 26 Syrian troops and 74 civilians, including 16 children.[64] In addition, 16 Turkish troops were killed in Syria.[64]
In the months leading up to the2024 Syrian opposition offensives that led to thefall of the Assad regime, Turkey sought a reconciliation with Assad to mitigate the threat to Turkey from Kurdish militias and discuss the resettlement of Syrian refugees. The Assad regime insisted on the complete withdrawal of Turkish forces from Syria, a demand which was echoed by Russia in November 2024. On 27 November 2024, Syrian opposition forces launched an offensive against the Assad regime, a move which analysts say would have been impossible without a green light from Turkey.[358][359]
Following the fall of the Assad regime, Turkey and Turkish-backedSyrian National Army fighters in northern Syria continued their offensive against U.S.-backedSyrian Democratic Forces.[360][361] The Syrian rebels' quick progress against the Assad regime paved the way for arenewed Turkish offensive against Kurdish forces. Beginning on 30 November 2024 withOperation Dawn of Freedom, the offensive aims to expand Turkish-controlled territory, weaken the SDF, prevent Kurdish autonomy in post-Assad Syria, and align with Turkish initiatives to establish a 30-kilometer deep buffer zone in northern Syria.[362][363][364] On 9 December 2024, SNA fighters captured the city of Manbij,[365] and the subsequent Kobani offensive was launched with the intent to capture the Kurdish-majority city of Kobani.[366]
Supporters of the Turkish Labour Party protesting in London following the2015 Ankara bombings
Between 2015 and 2016, ISIL performed numerous terror attacks in Turkey. On 7 July 2015, reports surfaced that Turkish security forces seized a truck bound for Syria loaded with 10,000 detonators and explosive primers with total length of 290,000 metres (950,000 feet) inAkcakale, Sanliurfa province, southeastern Turkey. Five people were arrested; the detainees said they attempted to cross the border from the village of Aegean intoTell Abyad city inAl-Raqqah Province.[367] On 20 July,Suruç's municipal culture center, located inŞanlıurfa Province, was bombed by a Turkish ISIL member,[368] killing 32 people and hospitalizing at least 100 people.[369] On 10 October 2015 at 10:04 local time (EEST) inAnkara, two bombs were detonated outsideAnkara Central railway station. With a death toll of 103 civilians,[370] the attack surpassed the2013 Reyhanlı car bombings as the deadliest terror attack inmodern Turkish history.[371] Another 500 people were injured.[372]
ISIL has also employed suicide bombers in terror attacks in Turkey; on 19 March 2016, asuicide bombing took place inIstanbul'sBeyoğlu district in front of thedistrict governor's office. The attack occurred at 10:55 (EET) at the intersection of Balo Street withİstiklal Avenue,[373] a central shopping street.[374] The attack kiled at least five people,[375] including the perpetrator. 36 people were injured, including seven whose injuries were severe.[373][374] Among those injured were twelve foreign tourists,[374] and among those killed, two were ofdual Israel-U.S. nationality.[376] On 22 March, the Turkish interior minister said that the bomber had links withISIL.[377] On 28 June, ISIL militantsattacked Istanbul's Atatürk Airport. The three suicide bombers opened fire at passengers before blowing themselves up. The attacks left 45 dead and 230 wounded.[378]
In April 2016, Turkish artillery strikes killed 37 ISIL militants,[379][380][381][382] and 22 people were wounded by ISIL rocket projectiles hitting the border province ofKilis.[383] The Turkish Foreign Ministry has demanded raising awareness on Kilis to theUnited States Department of State. Turkey also demanded the deployment ofM142 HIMARS rocket launchers at the Turkish–Syrian border, under the belief that such moves would push ISIL militants southwards, leaving the border province of Kilis out of battery ranges.[384]
From 3 May to 6 May 2016, rocket missiles struck Kilis from ISIS-controlled territory, with the Turkish Army responding with fire at every attack.[385] The governor's office in Kilis released an official statement declaring the province a "special security area", which was effective from 5 May to 20 May at 5:00 p.m.[386] During the morning hours of May 7, the Turkish military carried out four separate air strikes against ISIL positions in northern Syria, with the assistance of U.S.-led coalition forces. Two Katyusha rockets were fired on the southeastern province of Kilis following the air strikes; in response, Turkish armed forces shelled ISIL targets with howitzers from the border. That evening, reconnaissance vehicles spotted ISIL positions inSawran, Aleppo Governorate, and northwest ofTell el-Hammam.[387] From 11 to 15 May, a total of 55 ISIL militants were killed in a Turkish and U.S.-led coalition, Turkish security sources have said.[388][389]
On 30 April 2023, Erdoğan announced that theTurkish National Intelligence Organization had allegedly tracked down and killed ISIS leaderAbu al-Hussein al-Husseini al-Qurashi the previous day.[390] Turkish media reported that the operation occurred atJindires, in a region controlled by Turkish-backed rebel groups, in which Abu al-Hussein detonated his suicide vest to avoid being captured.[391] However, the United States could not verify claims by Turkey that its forces killed al-Qurashi.[392] In August 2023, ISIS said al-Qurashi was killed during clashes with theTahrir al-Sham (HTS), whom it accused of being Turkish agents.[358] The United States believes the HTS is behind the killing despite the latter's denials.[393][394]
In late 2019, there were signs of a schism between Turkey and otherNATO members, in which the Turkish government was aware that NATO did not hold much leverage in regards to Turkish interventions.[395] Furthermore, United States President Trump, as well as U.S. military and diplomatic officials, has cited the NATO membership of Turkey as a key reason that the U.S. cannot be involved in the conflict between the Turkish and Syrian Kurdish forces.[396] Meanwhile, due to Turkey's strategic position between Europe and the Middle East, the NATO alliance members have limited themselves to relatively muted criticism.[397]
Numerous issues in resolving the conflict emerged at the2019 London NATO summit. PresidentEmmanuel Macron of France highlighted major differences with Turkey over the definition of terrorism, and said there was little chance this aspect of the conflict could be resolved positively.[398] Macron criticized Turkey for fighting against groups who had been allied with France and the West in fighting terrorism.[399][400] Turkey proposed a safe zone where Syrian refugees could be relocated, but this idea did not receive support from all parties.[399] One professed "exclusive" press report claimed that prior to the NATO Summit, there was a meeting at 10 Downing Street of the leaders of France, the United Kingdom, Germany and Turkey. One key point that emerged was that the Western countries insisted that refugees could only be relocated voluntarily.[401] Meanwhile, there were concerns in NATO about Turkey's growing closeness with Russia.[402]
Turkish and U.S. soldiers rendezvous in theNorthern Syria Buffer Zone, September 2019Turkish and U.S. soldiers providing security for a joint ground patrol in the Northern Syria Buffer Zone, 24 September 2019
In May 2016, Turkish Foreign MinisterMevlut Cavusoglu was angered by a series of photos which showed U.S. special forces in Syria wearing the insignia of the YPJ during joint operations against the Islamic State (IS). He called the U.S. "two-faced" and said the practice was "unacceptable", but Pentagon press secretary Peter Cook said it is common for American soldiers to attempt to blend in with local partners.[403] According to Çavuşoğlu, Turkey proposed a detailed plan to the U.S. for a joint military operation against jihadists inside Syria with the Americans and other allied troops, but U.S. officials denied it and said that Turkey had only offered a few basic concepts which involved joint efforts that only supported non-Kurdish forces.[404]
After U.S. forces allowed the October 2019 Turkish incursion into northeastern Syria, the Trump administration was criticized for prioritizing Turkey over its Kurdish allies. Abdi expressed his disappointment over the situation, asking "How can we best protect our people? And is the United States still our ally?"[405][406] Several American lawmakers criticized the apparent abandonment, remarking that it undermined U.S. credibility as an ally while only benefiting Russia, Iran, and Assad's government.[407]
On 13 October 2014, Turkey denied the United States from usingIncirlik Air Base for attacking ISIS militants in Syria,[408] which frustrated the U.S., whose efforts to build an international coalition to tackle ISIS forces from the air were partly hobbled by the difficulty of getting Turkey engaged.[409] After long negotiations with the U.S., on 23 July 2015, Turkey allowed U.S. planes to launch airstrikes against Islamic State militants. U.S. officials declined to give details of the agreement with Turkey.[410] On 25 February 2016, Saudi Arabian warplanes began arriving at the base as part of an anti-ISIS build-up being deployed over Syria, adding to U.S., German and British aircraft already using the base.[411][412][413] The families of U.S. troops and civilian personnel stationed at Incirlik Air Base left the base on 2 and 3 April 2016, following an order bythe Pentagon and the U.S. State Department to leave several areas of Turkey for their security.[414]
The New York Times reported that in response to the October 2019 Turkish intervention, the U.S. was reviewing the potential withdrawal of itsnuclear weapons from Incirlik Air Base under NATO'snuclear sharing.[415][416] Republican senator Lindsey Graham[417][418] and Democratic representativeEric Swalwell called for possibly suspending Turkey's membership in NATO.[419]
The Turco-Russian confrontation took place between Turkey and, initially, the Syrian government, and turned into a military crisis between Turkey and Russia after November 2015, when theTurkish Air Force shot down a RussianSukhoi Su-24 operating in Northern Latakia after a reported airspace violation.[135] Increased Russian military intervention on behalf of the Syrian Government and hostile Turkish territorial responses have all contributed to increasing escalation. Aerial confrontations between two nations have grown more common. Turkey said theRussian Armed Forces violated Turkish sovereign airspace committedwar crimes against Syrian Turkmens.[420] The Russian military has said Turkey had illegal economic ties withISIS and was planningmilitary intervention in Syria.[421][422]
Bilateral tensions gradually improved following the shootdown. On 22 February 2016, U.S. and Russia announced a deal for a truce to take effect in Syria on 27 February, referred to as a "cessation of hostilities", but the Turkish government did not cooperate. On 24 February, Erdoğan, during a speech said that "the PYD and the YPG need to be out of the scope of the cease-fire, just like Daesh (ISIL) is."[280] On 25 February, Turkish prime ministerAhmet Davutoğlu said that Turkey would not comply with the truce: "This deal is not binding for us when a party is of threat to Turkey, when Turkey's security is at stake".[423]
On 26 June 2016, Erdoğan wrote to Russian PresidentVladimir Putin, offering condolences to the family of the deceased Russian pilot of the Sukhoi Su-24 warplane that shot down. TheKremlin Regiment has asked for a personal apology for months, and a Turkish spokesman said this is a step toward improving bilateral relations between the two countries.[221] On 1 July 2016, Turkish and Russian foreign ministers said that the two countries will "coordinate" their policies over Syria.[424] On 7 October 2017, Turkish forces launched anoperation to establish observation posts in the northernIdlib Governorate, in coordination with Russia.[425]
In December 2015, Erdoğan rejected to join the anti-ISILRussia–Syria–Iran–Iraq coalition, due to the presence of Syria's president Bashar al-Assad.[426] During anInternational Syria Support Group meeting in Vienna on 17 May 2016, Turkish Foreign MinisterMevlüt Çavuşoğlu told Lavrov that he would resign if Moscow has any evidence that Turkey is helping ISIL.[427]
A new round of meetings for theAstana summit process took place in December 2019. The meeting included Russia, Syria, Turkey and Iran.[428] Several experts said the conflict was slowly moving towards resolution, and Russian political scientist Konstantin Truevstev said that Turkey, Russia, and Iran, the three parties involved in the Astana diplomatic process, were interested in resolving the conflict. Experts also said that Bashar al-Assad had made progress in restoring rule by local councils in areas affected by the conflict.[429]
FollowingOperation Peace Spring, Turkey and Russia increased collaboration in northern Syria. Several commentators in Moscow stated at the time that the situation was not in immediate Russian interests, as the Turkish intervention in Syria clashed with Russia's backing of the Syrian government in the region, but it provided opportunities for Russia as a mediator as the U.S. withdrew from Syria.[430]
On 15 October 2019, the Russian Ministry of Defense announced that Russian forces had started patrolling the region along the line of contact between Turkish and Syrian forces,[431] indicating that Russia was filling the security vacuum from the sudden U.S. withdrawal.[432]
Meanwhile, Russia arranged for negotiations between the Syrian government in Damascus and the Kurdish-led forces. Alexander Lavrentiev, Russia's special envoy on Syria, warned against the Turkish offensive into Syria, stating that Russia was seeking to prevent conflict between Turkish and Syrian troops.[433] SDF commander-in-chiefMazloum Abdi announced[when?] that they were ready to partner withVladimir Putin and Assad, stating that "if we have to choose between compromises and the genocide of our people, we will surely choose life for our people."[406] According to Syrian Kurdish officials, the deal allowed Syrian government forces to take over security in some border areas, but their own administration would maintain control of local institutions.[434] On the other hand, Russia said it would pledge to replace Turkish forces with Russian forces at a key highway in northern Syria.[435] It was reported that the Russian and Turkish armies had made a deal in which electricity would be supplied to Tell Abyad by Russia's allies, the Kurdish-led SDF who support Assad; while water would be supplied by the Turkish-controlled Alouk water station.[436] This deal was mainly facilitated by Russian military officials.[437] In December 2019, under the supervision of Russian armoured vehicles, Turkey withdrew all of its forces from al-Shirkark silos, which hold important supplies of wheat.[438]
Mustafa Bali, head of the SDF, said there were some agreements on the ground with the Syrian government for Syrian forces to be deployed along the border.[439] Russian military officials forged agreements between Syria, Turkey and Kurds for areas to be patrolled by each side.[440] In December 2019, Russian and Turkish forces resumed their joint patrols,[350] but questions remained about how much control Turkey has over its proxies, such as the Free Syrian Army.[441]
A former ISIS member mentioned[when?] that the ISIS groups were given free rein by Turkey's army, as Turkey's targeting of Syrian Kurds made a positive impression on ISIS.[228] Turkish security forces dispersed Kurds who had gathered at the border to cross into Syria and fight with Kurdish militants against ISIS.[442]
Turkey, in January 2016, denied Kurdish groups from northern Syria to take part in peace talks in Geneva, as Davutoğlu deemed the participation of the YPG a 'direct threat' to his country.[443] In February 2016, the U.S. urged Turkey to stop the shelling of the Kurds and focus on fighting ISIL.[444] On 17 February 2016, at least 500 armed fighters crossed the Turkish border heading for the Syrian town of Azaz to fight against the Kurdish forces, according to the head of the SOHR.[445] After theFebruary 2016 Ankara bombing, the head of the Syrian Kurdish Democratic Union Party (PYD) denied any involvement and said that Turkey used the attack as a "pretext" to intervene in Syria.[446]
On 13 March 2016, Russian Foreign MinisterSergey Lavrov said Russia has evidence of Turkey's "creeping expansion" in northern Syria, as Turkey was fortifying positions in Syria hundreds of metres from the border, and sending its military across the Syrian border to prevent local Kurdish groups from consolidating their positions.[447][448] Turkey denied Lavrov's claims.[449]
In 2018, an ex-ISIS source said Turkey was recruiting and retraining ISIS fighters in order to participate in theTurkish military operation in Afrin against the Kurds.[450] In addition, in a statement carried byAl Jazeera Arabic,The Pentagon said that Turkish military operations in Afrin are impeding the task to eliminate ISIS.[451]
In October 2019, Republican SenatorLindsey Graham stated he would "introduce bipartisan sanctions against Turkey if they invade Syria" and request that Turkey be suspended from NATO if they went after U.S.-allied Kurdish forces who aided "in the destruction of the ISIS Caliphate".[452] Moreover, theInternational Bar Association condemned the assaults against Syrian Kurds by Turkish forces in northern Syria, and called on Turkey to halt the attacks and respect the civilians as it is obligated by international laws, after the reports of Turkish-backed militias executing civilians.[453]
Former U.S. Vice PresidentJoe Biden apologised for saying Turkey was supporting jihadis in a speech atHarvard'sKennedy School on 2 October 2014.[454]
Ever since theIslamic State of Iraq and the Levant (ISIL) was founded from itsIslamist predecessor groups in June 2014, Turkey has faced numerous allegations of collaboration with and support for ISIL in international media.[227][228][455][456] Turkish authorities have also openly supportedal-Qaeda and other extremist Islamist groups likeAhrar al-Sham,[457] andal-Nusra Front, which is proscribed as a terror organization by much of the U.S. and Europe.[458] In addition, the SOHR said that the vehicle used in a car bombing attack inKobanî, in which Islamic State snipers were hiding in grain depots on the Turkish side of the border and firing on the town,[459] had come from Turkish territory.[460] In late 2014, several ISIL fighters and commanders, as well asDavid L. Phillips ofColumbia University's Institute for the Study of Human Rights,[227] said that Turkey supported ISIL.[461][462][463] Within Turkey itself, ISIL is reported to have caused increasing political polarisation between secularists and Islamists.[464]
On the other hand, journalistPatrick Cockburn wrote in late 2014 that the "exact nature of the relationship [between Turkey and ISIS] remains cloudy",[465] and in 2015, Cypriot Foreign MinisterIoannis Kasoulidis questioned Turkey's determination to fight ISIS.[466] In an email toThe Guardian,Noam Chomsky called Erdoğan hypocritical for blaming ISIS for theJanuary 2016 Istanbul bombing while supporting ISIS andal-Nusra Front.[467] In July 2014,James Carver, aMember of the European Parliament, made two questions in theEuropean Commission after some press reports about Turkish support for ISIS.[468][469] In August, the Commission responded that there is no evidence to support press allegations, adding that theTurkish Ministry of Foreign Affairs has repeatedly dismissed them, and that ISIS poses a significant security threat to Turkey.[470] In late November 2015, Turkey implemented tougher controls to stop ISIL militants crossing on a 60-mile stretch of the border with Syria where ISIL had control of the Syrian side. The crossing was used for smuggling and arms transfers. This followed Russian PresidentVladimir Putin directly saying that Turkey was aiding ISIL and al-Qaeda, and after theNovember 2015 Paris attacks, Turkey under pressure from the U.S. to close its borders to ISIS.[471]
Despite the allegations, Turkey has fought against ISIL in numerous instances. On 23 July 2015, a Turkish sergeant was killed by fire from ISIL forces in Syria, and four Turkish tanks returned fire into ISIL held territory in Syria.[472] The following day, the Turkish government announced that in order to prevent an attempted invasion by ISIL troops,[473] TurkishF-16 Fighting Falcons struck ISIL targets across the border fromKilis Province withsmart bombs, marking a dangerous new escalation between the two parties.[474][475] According to a U.S. report, the Turkish strikes in September and October 2023 caused the SDF, which was previously working with Coalition forces, to halt operations against ISIS. Furthermore, Turkish forces killed SDF personnel, including senior commanders, and the Turkish strikes caused tensions between the SDF and U.S. forces, partly because Turkey and the United States are allies.[476]
Turkey was further criticized for allowing individuals to enter the country and join ISIL in Syria,[477][478] as well as training ISIS members and allowing jihadist groups to move through its territory in order to reach other countries.[227][479] American websiteAl-Monitor stated in June 2014 that Turkey had allowed ISIL to let thousands of international jihadists and other supplies reach Syria through the Turkish border,[480][481] and in a 2014 interview, former U.S. ambassador to TurkeyFrancis Ricciardone said that Turkey has directly supportedal-Qaeda in Syria, adding that Turkey did nothing to distinguish between "moderate" groups and extremists.[457] In 2015, the chief of theCypriot Intelligence Service (CIS) said that people in theTurkish Republic of Northern Cyprus could be helping ISIL members travel between Europe and Syria. He added that the CIS had received intelligence of a group of ISIL sympathizers who were traveling to the Greek Cypriot-controlled south of the island and had blocked their entry before sending them back.[482] An ISIL commander stated that a majority of the soldiers, weapons, and supplies came from Turkey, adding that ISIL fighters received treatment in Turkish hospitals.[463] On 10 February 2016, Russian AmbassadorVitaly Churkin informed the UN Security Council about a reported ISIL recruitment network based inAntalya, targeting fighters from the formerSoviet Union. He noted that in September 2015, around 1,000 IS fighters from Europe and Central Asia were moved from Turkey to Syria viaGaziantep. Additionally, he said that Turkish intelligence aided in relocating ethnic Tatars fighting for al-Nusra Front and facilitated the transport of ISIL militants from Syria to Yemen using Turkish military air transport and maritime routes to theport of Aden.[483]
Former Syrian president Bashar al-Assad has repeatedly condemned Turkey's affiliation with terrorist organizations; during a 2015 interview, Assad mentioned that military and logistic support from Turkey was the key factor in the2015 Idlib offensive. He also blamed Turkey for the failure of a humanitarian ceasefire plan inAleppo.[484] His sentiment was shared by Iranian analysts, who said that Turkey is the main culprit in supporting the terrorist movements of ISIL.[485] In May 2018, Assad deprecated Erdoğan's affiliation with theMuslim Brotherhood, which is considered a terrorist organization in Syria.[486] In another interview, in August 2023, Assad accused Turkey of terrorism and violence in Syria.[487]
In January 2016,The Guardian revealed documents indicating that ISIL managed a complex immigration operation via the Syrian town of Tell Abyad, which remained open until Kurdish forces captured it during theTell Abyad offensive. Aymenn al-Tamimi, a researcher on ISIS documents, confirmed the authenticity of the manifests, noting their alignment with ISIS bus routes. A senior Turkish official claimed Turkey was actively working to halt the influx of foreign fighters and targeting recruitment and logistics networks referenced in the documents.[488] In July 2016, a leaked confidential report produced by the German Interior Ministry said Turkey was supporting terrorist groups across the Middle East including various Islamist groups fighting in Syria. The report showed that Germany sees Turkey as platform for Islamist groups in the Middle East.[489]Anonymous launched cyber-attacks on Turkey[when?] after saying it was supporting ISIS by buying oil from them and treating their wounded in hospital. They have also said that they will continue the attacks as long as Turkey is supporting ISIS.[490]
In 2019, theUnited States Department of the Treasury imposed sanctions on Turkish individuals and companies for providing financial support to the ISIS. The sanctions raised questions about the Turkish commitment to fight the ISIS networks inside Turkey.[491][492] In 2021, sanctions were imposed on Alaa Khanfurah and his Turkey-based money service business, because in 2017-2020, they provided support to ISIS throughout Syria.[493]
Turkey's state intelligence agency, the MİT, were said by Turkish judicial sources talking to Reuters to be delivering arms to IS-controlled parts of Syria during late 2013 and early 2014.[494] Turkish journalists reporting this were charged with spying and "divulging state secrets" by the Turkish court,[495] and Turkish officers have also faced spying charges for intercepting some of the intelligence agency's weapon-filled trucks.[496] Furthermore, the Turkish government gave orders to the officers to let the trucks pass into Syria. In June 2019, a Turkish court convicted the group officers and prosecutors, who stopped the MİT trucks, to over 20 years in prison for obtaining and disclosing confidential state documents. They were also said to beFETÖ members.[497] In December 2020, the Turkish court sentenced 27 people to prison for stopping the MİT trucks in 2014.[498]
According to documents revealed in 2019, the Turkish National Intelligence Organization (MİT) was secretly transporting ammunition and fighters into Syria with buses in 2015.[499] In addition, Turkish newspaperCumhuriyet published video footage which it said showed security forces discovering weapons parts being sent to Syria on trucks belonging to the MİT.[500]
On 18 March 2016, Russia's UN Ambassador Vitaly Churkin sent a letter to the UN Security Council saying that three Turkish humanitarian organizations (NGOs) sent weapons and supplies to extremists in Syria on behalf of the MİT. The three NGOs were the Besar Foundation, the Iyilikder Foundation and theFoundation for Human Rights and Freedoms (IHH).[501] In February 2016, Kılıçdaroğlu said that the Turkish government has sent arms to jihadist groups in Syria and built jihadist training camp in Turkey.[502] In addition, in a 2018 interview, former Turkish National Police official Ahmet Yayla said that the MİT has used Turkey's IHH as an intermediary to arm Islamist terrorists.[503]
In February 2022, the Turkish intelligence captured and abducted from Ukraine the Turkish arm dealer and former special forces captain in the Turkish armed forces, Nuri Bozkir, after he exposed the Turkish arms transfers to militant groups in Syria and Libya. In an interview before his arrest, he said that he bought weapons in eastern European countries and shipped them to Turkey, then the Turkish intelligence sent them to battlefields across the region.[504]
In late 2015, Iraqi Prime MinisterHaider al-Abadi said that most of the oil produced in Islamic State-held territory in Iraq and Syria was being smuggled through Turkey,[505] and Iran's Secretary of theExpediency Discernment Council said that Iran has photographs of truck tankers bringing oil to Turkey from ISIS.[506] Al-Abadi also mentioned that he sees no evidence that Turkey wants to fight ISIS, and that Turkey wants to revive theOttoman Empire.[507]
In September 2014, western intelligence officials said that they can track the ISIS oil shipments as they move across Iraq and into Turkey's southern border regions. The Obama administration was struggling to cut off the millions of dollars in oil revenue made by ISIS, but they were unable to persuade Turkey.[508] In addition, former Iraqi member of ParliamentMowaffak al-Rubaie said Turkey was turning a blind eye to the black market ISIS oil trade.[509] In June 2014, a member of Turkey's parliamentary opposition, Ali Edibogluan, said that IS had smuggled $800 million worth of oil into Turkey from Syria and Iraq.[510] Sadik Al Hiseni, the head of the security committee in the city of Diyala in Iraq, says they have arrested several Turkish tankers trying to take ISIS oil out of the province of Salahuddin.[511]
Israeli defence ministerMoshe Ya'alon has said Turkey was buying oil from ISIS and funding ISIS militants.[479] According toThe Jerusalem Post, Turkey was selling the oil and sharing some of the earnings with ISIS, but the oil exports stopped in December 2015 after Russia bombed the tankers which transferred the oil to Turkey.[512] A U.S.-led raid, during which the ISIS official responsible for oil smuggling,Abu Sayyaf, was killed, produced evidence that Turkish officials directly dealt with ranking ISIS members.[458]
In October 2019, anAmnesty International report accused Turkey and its allies for war crimes.[513]Kumi Naidoo said that the Turkish military and their allies do not care about civilian lives.[514]Furthermore, USA special envoy for Syria said that they had seen evidence of war crimes during Turkey's offensive against the Kurds in Syria, and had demanded an explanation from Turkey. U.S. officials were investigating a report that therestricted burning white phosphorus had been used during the Turkish offensive. Turkish officials have denied that war crimes were committed.[515] TheUnited States Secretary of Defense,Mark Esper, said in an interview that Turkey "appears to be" committing war crimes in Syria, adding that there was footage showing the execution of Kurdish captives.[516][517]
In November 2019, Turkish-commanded forces were accused of committing war crimes after mobile phone footage was revealed. The UN has warned that Turkey could be held responsible for the actions of its allies, while Turkey has promised to investigate.[518] In addition, U.S. drones appeared to show Turkish-backed forces targeting civilians during their assault on Kurdish areas in Syria, these actions reported as possible war crimes.[519][520] U.S. State Department spokeswomanMorgan Ortagus told CNN they received reports "that the Turkish-Supported Opposition may have engaged in violations of the law of armed conflict in northeast Syria, including reports of the killing of unarmed civilians and prisoners and reports of ethnic cleansing," adding that "those concerns remain."[520]
In March 2020, a UN report accused Turkish-allied rebels of abuses on Kurdish-held areas during an assault, adding if the rebels were acting under the control of Turkish forces, the Turkish commanders may be liable for war crimes. In addition, it called on Turkey to investigate whether it was responsible for an air raid on a civilian convoy nearRas al-Ayn. Turkey denied a role in the attack, while the SOHR said that it was conducted by Turkish aircraft.[521]
In September 2020, the United Nations asked Turkey to investigate possible war crimes and other human rights violations carried out by Turkish-affiliated groups in the area that Turkey controls in Syria. Turkey accused the UN Human Rights Office of baseless claims and "undue criticism".[522] TheOffice of the United Nations High Commissioner for Human Rights said that in the areas controlled by Turkey the number of crimes against civilians have been increased.[523]
The 2021 and 2022Country Reports on Human Rights Practices, the UN Commission of Inquiry for Syria, theOffice of the United Nations High Commissioner for Human Rights, and human rights organizations mentioned that Turkish-affiliated groups committed human rights abuses in Syria, including killings, torture, sexual violence, transfer of detained civilians across the border into Turkey, enforce demographic change targeting Kurdish Syrians, recruitment of child soldiers, the looting and desecration of religious sites and private property and more.[524][525] Furthermore, the Turkish-supportedSultan Murad Division andAhrar al-Sharqiya have been accused of war crimes.[526][524] By August 2022,Airwars estimated that 736–1,189 civilians were killed by Turkish airstrikes in Syria and Iraq since 2015, including 146-170 children, 104-119 women, and 1,400 named victims. The Turkish military has denied that any of its strikes have resulted in civilian casualties.[137]
Turkey launched 339 attacks on North and East Syria in early 2024, killing five civilians and injuring 52, according to the Syrian Democratic Forces. The attacks severely damaged infrastructure and essential services, with the SDF and international law experts labeling these actions as war crimes.[527]
The Turkish government has targeted journalists that have covered scandals and events of the Syrian civil war,[528] and, throughAhrar al-Sharqiya, murdered the Kurdish-Syrian politicianHevrin Khalaf in 2019.[520][524] In 2014,Serena Shim, a journalist ofPress TV, died in a car crash with a heavy vehicle in Suruç, Turkey, in what are said, by her employer and her parents, to be suspicious circumstances. The car crash happened just days after she said that theMİT had threatened her and said she was spying, due to some of the stories she had covered about Turkey's stance on ISIL militants in Kobane. She also said that she had received images of ISIL militants crossing the Turkish border into Syria in World Food Organization and other NGOs trucks.[529][530][531]
In 2016, Russian envoyVitaly Churkin reported in an official letter to the UN about the export of antiquities from Syria and Iraq to Turkey, primarily through Gaziantep, where they were illegally auctioned. He noted the emergence of new smuggling hubs on the Turkish-Syrian border, facilitated by Turkish transport companies. Smuggled items reach İzmir, Mersin, and Antalya, where international criminal groups create counterfeit documentation for the artifacts. Turkey has pledged to investigate these allegations, asserting that they are politically motivated.[532] In 2015, Syria's antiquities chief said Turkey refused to return looted objects from ancient heritage sites in Syria or to provide information about them.[533] Also, Turkey said that it allows ISIL to smuggle Syrian antiquities through it.[534]
Reports emerged again in 2019 that, followingOperation Olive Branch, more than 16,000 artifacts such as glass, pottery and mosaics, mostly fromAfrin District, were looted and smuggled to Turkey by Syrian rebels.[535] In 2022, the Russian Defence Ministry said that Turkish-backed forces illegally performed excavations in northern Syria by using explosives and heavy equipment that destroy ancient sites. Many also accused Turkey of turning a blind eye to these activities. Turkey, in response, deployed soldiers in some of the ancient sites in Syria and started operation to retrieve smuggled Syrian items in Turkey.[536]
In March 2020, nongovernmental organizations, theWorld Health Organization and the Kurdish-led administration in northeast Syria said that the water supply from the Alouk pumping station had been repeatedly interrupted after Turkey and its allies took control of the Alouk water station after the Turkish offensive in October 2019. In addition, local authorities and humanitarian groups in Northeast Syria said that they are unable to bring additional supplies into the region because the border with the Kurdistan Region of Iraq is closed. They all warned against doing these in the midst of theCOVID-19 pandemic.[537][538][539]
In July 2021, the U.S. added Turkey to the list of countries that implicated in the use of child soldiers, because it used them in Syria and Libya.[544] Furthermore, the 2021 and 2022 Country Reports on Human Rights Practices mentioned the recruitment of child soldiers from Turkish-supported forces.[524][525] The Turkish government-linked think tank SETA withdrew a report detailing the composition of theSyrian National Army as it revealed the use of child soldiers. In addition, according to a report by Al-Monitor, citing sources on the ground, Turkey has deployed child soldiers to Libya from Syria,[545][546] and the 2021, 2022, and 2023 Trafficking in Persons Reports mentioned that Turkey provided operational, equipment and financial support to armed groups in Syria which recruit and use child soldiers.[547][548][549]
A study by Metropoll in September 2019 found that 68% of Turks disapproved of the government's policies on Syria.[550] The poll also found that 47.5% of Turks see the Free Syrian Army as an enemy. Three out of four Turks said that Syrian refugees should return to Syria regardless of whether the civil war continued or not.[551] According to another survey by Metropoll, the amount of support for the2019 Turkish offensive into north-eastern Syria was at 79%, whileOperation Olive Branch had 71% support.[552]
