Following months of tension and threats, the first agreement to establish theNorthern Syria Buffer Zone was reached in mid-August 2019, between theSyrian Democratic Forces (SDF) and the United States on the one hand, and Turkey on the other. The deal aimed to limit the Turkish offensive on Syria's north through a process of gradual withdrawal of SDF, removal of fortifications and joint US-Turkish monitoring and patrols, while still allowing the area to remain under the civil control of theAutonomous Administration of North and East Syria and the military control of theSyrian Democratic Forces military councils as per the first buffer zone agreement. Despite initial progress in its implementation,[a] Turkey grew more and more dissatisfied with it, issuing more demands which were rejected by the SDF.[7][8]
In early October that same year, following a phone call between Turkish PresidentRecep Tayyip Erdoğan and US PresidentDonald Trump, Trump announced the withdrawal of US forces from the region, which allowed Erdoğan to dismiss the first buffer zone deal and launch his2019 offensive into north-eastern Syria against the SDF, which Turkey considers to be an extension of theKurdistan Workers' Party, an organization designated by Turkey as a terrorist group.[9] Having previously dismantled their fortifications and having their positions observed as part of the first deal, and now stripped of military backing, SDF units reportedly faced a "desperate" challenge in having to defend their territory against both theTurkish Army and the rebelSyrian National Army.[10][11] Despite initially offering armed resistance, SDF units were nonetheless forced to withdraw, triggering a wave of over 300,000 displaced people, amid Kurdish fears that Turkey would resort toethnic cleansing against the Kurdish population.[12] AlthoughTurkey's invasion was widely condemned internationally, the SDF stood little chance against the Turkish Army and the SNA.[11] Amid what one SDF commander described as a choice between "compromise andgenocide", the SDF turned to theSyrian Government,with which they have had a lukewarm relationship, for help.[13][14]
The United States negotiated a 5-day ceasefire in Northern Syria on October 17, which required the SDF to withdraw from the border areas, but at the same time allowed the SDF time to negotiate further with Russia and the Syrian government.[15]
Seeking to avoid further expansion of Turkish control within Syria's territory,Bashar al-Assad's government agreed to a deal with the SDF to move theSyrian Army into the border areas.[16] Subsequently, the Syrian Army entered several SDF-held towns and positioned troops on the seam lines between the two sides in a bid to stop the Turkish offensive.[17][18][19]
The deal was struck shortly after the entry of Syrian army troops into SDF-held territories.[20]

The agreement was negotiated between Russian PresidentVladimir Putin and Turkish PresidentRecep Tayyip Erdoğan on 22 October 2019, at a diplomatic summit in the Russian resort town ofSochi.[1] The negotiation of the agreement took six and a half hours to conclude.[21]
A buffer zone would be established in Northern Syria. The zone would be around30 kilometres (19 mi) deep,[b] stretching fromEuphrates River toTall Abyad and fromRas al-Ayn to the Iraq-Syria border, but excluding the town ofQamishli, the Kurds'de facto capital.[c]
AllYPG forces, which constitute the majority of the SDF, must withdraw from the buffer zone entirely, along with their weapons, within 150 hours from the announcement of the deal. Their withdrawal would be overseen by Russian Military Police and the Syrian Border Guards, which would enter the zone at noon on 23 October.
Following the YPG withdrawal, joint Russian-Turkish ground patrols would be held in the buffer zone area, but only within10 kilometres (6.2 mi) from the border and not including Qamishli.[e][f]
Turkey would retain sole control of the areas it had captured during its offensive between the towns ofTell Abyad andRas al-Ayn.
On24 October 2019, the SDF said Turkey was violating the deal by launching a ground offensive against three villages in the country's north
Russia stated that the implementation of the zone was "on track" and announced that it was sending additional military policemen and heavy equipment to aid in its implementation.
The SDF announced that the Kurdish fighters had already withdrawn from the buffer zone.[31]
On27 October 2019, Turkey said an attack by Kurdish forces left one Turkish soldier dead and five others injured. Turkish forces responded within the framework of self-defence".[32]
TheSyrian Democratic Forces officially announced their support for the deal, stating that their fighters would deploy to new positions deeper into Syria, as they stated that Syrian Government border guards were taking up their previous positions along the border.[33][34]
On28 October 2019, following a large-scale deployment ofSyrian Army troops to various border villages in the few days prior, the Syrian Army deployed to the town ofAl-Darbasiyah along the Syrian-Turkish border for the first time in seven years.[35]
45 SDF vehicles carrying troops and heavy artillery departedAmuda and headed towards the country's south. The Syrian Government stated that the withdrawal had been carried out in coordination with the Syrian Army.[34]
On30 October 2019, the Turkish President announced that the joint Russian-Turkish ground patrols within the zone would begin on 1 November, but would be limited only to a7 kilometres (4.3 mi) deep area within the buffer zone. He however said, that the zone could be expanded to the full 10 kilometers, should SDF attacks on Turkey continue. The Turkish President further stated that he believed that the YPG withdrawal from the buffer zone had not fully taken place.[36]
On31 October 2019, heavy clashes took place between the Syrian Army and Turkish forces nearRas al-Ayn, after theSyrian National Army attacked several villages to the south of the town. Syrian state broadcasterSANA said the Turkish-backed forces were seizing a water plant and thus cutting off water to theAl-Hasakah Governorate.
Turkey's defence ministry announced that it had detained 18 people it suspected were Syrian Army servicemen, which had reportedly attacked Turkish forces near the town.[37] It further stated that it had immediately entered into negotiations with Russia to release the captured soldiers.[38]
TheSyrian Observatory for Human Rights stated that at least 5 Syrian Army servicemen had been killed by Turkish artillery shelling on the edge of the village of Assadiya. It also reported that Turkish-backed rebel groups had executed a captured Syrian Army soldier. The observatory added that clashes had continued past that point.[39]
The Syrian Army and Syrian Democratic Forces launched a joint counter-attack and reportedly recaptured some of the areas they had lost during the SNA's assault that same day, after shelling Turkish-backed forces with heavy artillery.[40]
The Syrian Army sent considerable reinforcements to the front line in an attempt to stop Turkish-backed forces from advancing.[41]
The SDF Commander,Mazloum Abdi, said Turkey was failing to adhere to the ceasefire agreement, stating that he believed Turkey had partnered with jihadists to occupy Christian villages and threatenAssyrians with "annihilation".[42] Another SDF spokesman stated that Turkish-backed forces had continued with their advance, including by attacking areas held by the Syrian Army. He stated that Turkey had used Syrian Airspace to aid its army and "its jihdaists" to attack the region.[43]
On1 November 2019, the first joint Russian-Turkish ground and air patrol was held within the buffer zone. The joint patrol covered 110 kilometres (68 mi) of territory along the border, going up to 7 km deep into Syrian territory - less than the 10 originally set out in the deal.[44][45]
Turkey released the 18 men which were taken prisoner the previous day.[44] This unilateral prisoner release caused considerable tensions within the ranks of theSyrian National Army, drawing criticism from some fighters that the release constituted "a betrayal of the religion". The Homs al-Adiyyeh Brigade of theSultan Murad Division of the SNA subsequently defected to joinJaysh al-Izza in protest.Ahrar al-Sharqiya also condemned the release, but blamedSalim Idris, who serves as Minister of Defence of the internationally unrecognizedSyrian Interim Government, instead of the Turkish government.[46]
On3 November 2019, theSyrian Observatory for Human Rights reported that the SDF had launched a large attack against Turkish-backed forces nearRas al-Ayn, subsequently managing to recapture 13 villages from them despite intensive artillery bombardment by the Turkish Army.[47]
On5 November 2019, the second round of joint Russian-Turkish ground patrols were held. Russian and Turkish military vehicles, observed by TurkishUAVs, patrolled for 160 kilometres (99 mi) in the area betweenKobanî andTell Abyad. Following the end of the patrol, the Turkish Armed Forces withdrew to the Turkish side of the border.[48][49] While patrolling near Kobani, the vehicles were pelted repeatedly with stones thrown by local residents.[50][51]
Turkish President Erdogan accused the United States of continuing to carry out joint patrols with theYPG in Syria. He further alleged that the YPG hadn't left their positions atManbij andTell Rifaat, as the second buffer deal required.[52][53] He attempted to justify the Turkish-backed forces' incursions outside of their zone of control in the previous few days by stating that he believed that SDF units had gathered on the edge of the Turkish control zone aroundRas al-Ayn and were preparing attacks on Turkish and Turkish-backed forces within the town itself.[54] He added that Turkey would continue to fight until the last "terrorist" was "neutralized".[55]
Syrian state media announced that the Syrian Army had deployed units near the town ofQamishli, in what it reported was a bid to "counter Turkey's aggression".[56]
On8 November 2019 a Syrian citizen was killed after being run over by a Turkish military vehicle, which was conducting a joint patrol with Russian forces. The man was reportedly a part of a group of residents which were throwing stones at the Turkish vehicles in protest of the joint patrols.[57]
The spokesman for the Kurdish-led SDF reported that Turkish troops had firedtear gas against anti-patrol protesters inAl-Malikiyah - which was under the joint control of SDF and American forces, but nonetheless part of the 10 km patrol zone. He further alleged that 10 civilians were injured by the gas. He accused Russia of complicity in both incidents, as the patrols were carried out under "Russia's auspices".[57][58]
Local residents released footage on social media, showing themselves once again throwing stones at Turkish armored vehicles during joint patrols, while ignoring their Russian counterparts.[59][60]
On9 November 2019, heavy clashes erupted between Syrian and Turkish forces along the buffer zone. Several people were injured, including aSANA reporter.[61][62]
The Syrian Democratic Forces released a statement in which they claimed to have killed 13 fighters belonging to theSyrian National Army in combat aroundAyn Issa, while sustaining 12 casualties themselves.[63]
TheTurkish Ministry of Defense stated that they had recorded a total of 8 alleged ceasefire violations by the SDF within a 24-hour period.[62]
On12 November 2019, the fifth round of the joint Russian-Turkish military patrols was diverted from its intended route near Kobani by local anti-patrol protesters, which attacked the Turkish vehicles with stones and fire extinguishers.[64][65] Nevertheless, the Turkish Defence Ministry stated that the patrols were continuing, despite what it termed to be "provocations by terrorists".[66][67]
On14 November 2019, sixth round of the joint Russian-Turkish military patrol completed a 45 km long area. Turkish Ministry of National Defense stated: "Turkish and Russian units accompanied by UAVs completed the sixth joint land patrol in the east of the Euphrates as planned".[68]
On16 November 2019, seventh round of the joint Russian-Turkish military patrol completed. Turkish Ministry of National Defense states: "Turkish and Russian units completed their seventh joint land patrol in the Qamishli-Derik sector with four vehicles each and UAV support in the east of the Euphrates."[69]
Joint patrols continued through 2019 and by27 January 2020, the Russian and Turkish Armed Forces had conducted a total of 23 joint patrols inside the buffer zone.[70] The final joint patrol reported by theSyrian Observatory for Human Rights was the 24th patrol held on30 January.[71]
Bylate January 2020, Russian forces repeatedly clashed with residual American troops left inside the zone. US forces based from an American base at al-Wazir intercepted a Russian patrol and prevented it from setting up a military base atAl-Kharitah. A verbal altrecation took place between the two sides and escalated into the raising of weapons, but a clash was prevented by SDF mediation.[72] A similar incident shortly thereafter was reported to have significantly increased tensions between the two sides.[73] Russia responded by deploying advancedair defence systems in itsQamishli airbase.[74]
On3 February 2020, American forces attempted to block Russian patrol on the M4 highway. The Russian patrol drove around the roadblock via dirt roads and sent several helicopters to fly over American forces. US military helicopters then began pursuing the Russian helicopters until they reachedRas al-Ayn airspace.[75] A similar incident occurred on4 February, this time with a Russian vehicle reportedlyramming a US armored vehicle which was blocking its path. Despite this, no military hostilities were reported to have taken place between the two sides.[76]
Russian-Turkish tensions and Turkish rejection of joint patrols
On1 February 2020, Russian Forces closed the border crossing betweenAmuda andAl-Darbasiyah, blocking it with large cement blocks. It had previously been opened by Turkey as the patrols began.[77]
On4 February 2020, the Turkish Armed Forces prevented a Russian military delegation from inspecting a water project near Olukah inAl-Hasakah, reportedly firing into the air in order to force the Russian forces to withdraw. TheSyrian Observatory for Human Rights opined that the incident demonstrated "increasing differences" between the two sides.[78]
Inearly February 2020 the Turkish Armed Forces refused to participate in joint patrols with their Russian counterparts twice. Turkish troops informed a Russian officer on6 February that they will not take part in the patrols and they were subsequently held by Russian forces alone.[77] That same day theSyrian Arab News Agency reported that theTell Tamer power station was put out of service as a result of what it stated were Turkish attacks against theoverhead power lines that fed the station. It also alleged that Turkish attacks had caused great damage to other local infrastructure, as well as killed a number of civilians in the area.[79]
Intermittent clashes and shelling occurred in early February, mostly as Turkish and pro-Turkish forces attacked SDF and government positions and made minor unsuccessful attempts to advance. Several casualties were reported.[80][81][82][83]
Russian patrol in al-Hasakah province, December 2020
Following multiple Turkish refusals to take part in joint patrols with their Russian counterparts, a joint patrol was finally held on17 February 2020, when 4 Russian and 4 Turkish vehicles patrolled parts of the buffer area together.[84]
By18 February 2020, joint Russian-Turkish patrols had resumed per their usual schedule.[85]

On9 December 2024, Russia withdrew from their bases inManbij andKobani.[88]
United Nations - On 1 November 2019 the UN Secretary-General met with President Erdogan of Turkey to discuss Turkey's proposal to relocate a large number of Syrian Refugees in Turkey to the Safe Zone. Mr. Guterres informed the Turkish President that the UNHCR will immediately form a team to study the proposal and engage in discussions with Turkish authorities, in line with its mandate.[89][90] The Secretary-General greenlighted the proposal but told the Turkish President that the relocations should be "voluntary, safe and dignified".[89]
Syrian Democratic Forces - The SDF stated that they consider themselves as "Syrian and a part of Syria", adding that they will agree to work with the Syrian Government.[91] The SDF officially announced their support for the deal on 27 October 2019, five days after the memorandum was made.[34][33]
Ba'athist Syria - Syrian PresidentBashar al-Assad thanked the Russian President for his role in the negotiation of the deal and expressed his full support for it. At the same time, he raised concerns about Turkish interference in Syrian affairs and dubbed Turkish President Erdogan a "thief".[25][92]
Turkey - Turkish PresidentRecep Tayyip Erdoğan threatened to forcefully "clear terrorists" from the Syrian-Turkish border should the deal fail. He further reiterated his threat to let the Syrian refugees residing in Turkey at that point to freely emigrate into Europe, if Turkey does not receive "support" in its plan for the relocation of 1 to 2 million refugees within the buffer zone in what the Turkish President dubbed the "first stage" of their return.[93]
Iran - Iran's foreign ministry called the agreement "a positive step" and stated that it "backed any move to restore stability in the region", the opposite of its stance on the priorNorthern Syria Buffer Zone.[25]
United States - US PresidentDonald Trump praised the deal that he viewed as allowing "someone else [to] fight over this long bloodstained land", following which he ordered the lifting of the sanctions that he had placed on Turkey nine days prior as a reaction to the start of Turkey's offensive.[94]
Germany - German ChancellorAngela Merkel proposed that the buffer zone be enforced through an international force. Turkish Foreign MinisterMevlüt Çavuşoğlu stated that such a plan was unrealistic.[95]
