The YPG and allied forces capture the Tell Tamer[6] and Ras al-Ayn countrysides,[7] including 230 towns, villages, and farms,[8] as well theAbd al-Aziz Mountains[6]
TheWestern al-Hasakah offensive was a military operation in the spring of 2015, waged between theKurdishYPG and allied forces against theIslamic State (ISIL) for control of the western half of theAl-Hasakah Governorate, during theSyrian Civil War. The Syrian Kurds' counteroffensive was dubbedOperation Commander Rûbar Qamishlo. During the initial ISIL offensive, Islamic State forces managed to advance up to the western banks of theKhabur River, reachingTell Tamer andRas al-Ayn, and capturing dozens of villages, in addition to abducting 350–400 Assyrian Christians as hostages.[4][5] In the subsequent Kurdish-led counteroffensive, the Kurdish-led forces managed to expel Islamic State forces from the western countryside of the al-Hasakah Governorate, in addition to theAbzulaziz mountain range. On 31 May 2015, as most of the offensive operations in the western Al-Hasakah Governorate ended, the part of the offensive in theRas al-Ayn Districtexpanded into the Tell Abyad region, in the northernRaqqa Governorate.
On 21 February 2021, theYPG and their allies launched an offensive on ISIL territory in the eastern countryside of the al-Hasakah Governorate, to expel the Islamic State from the region.[24][25] On 23 February, the YPG capturedTell Brak, during a pre-dawn raid,[26] and severed the road between Tal Hamis andal-Hawl two days later, which was a main ISIL supply line fromIraq.[27] On 27 February, Kurdish forces managed to capture the town ofTell Hamis and the surrounding area, while theSyrian Army launched their own offensive from the direction ofQamishli.[24][25] On March 10, the YPG had captured 103 villages and hamlets, in addition to Tell Brak and Tell Hamis, expelling ISIL to the south of the Khabur River.[24][28]

In response to the Kurdish offensive in the eastern al-Hasakah countryside, on 23 February 2015, ISIL launched a massive attack on a cluster of villages along the southern bank of theKhabur River around the town ofTell Tamer, in the western al-Hasakah countryside, using around 3,000 fighters and multiple tanks,[29][30][14] seizing 11 villages and kidnapping 220Assyrians by 26 February, according to theSOHR.[24][31] Local sources stated that 33–35 villages were captured[32][31] and put the number of abducted Assyrians at 350–400.[4][5] ISIL was reportedly withdrawing militants from other fronts in Syria, including the front atHoms, to boost their assault at Tell Tamer.[33] The Kurds managed to recapture several of the villages, but the fate of the Assyrians remained unknown.[34] It was also reported thatAbu Omar al-Shishani, ISIL's field commander in Syria, was leading the assault at Tell Tamer.[12]
On 28 February, ISIL executed 15 of their Assyrian hostages, 14 of whom were fighters. Another 13 Christian fighters were among those being held.[20] Kurdish-Arab allied forces were continuing to fight ISIL outside Tell Tamer, while the offensive in the eastern al-Hasakah countryside began drawing to a close.[35] By 3 March, 24 of the Assyrian hostages were released by ISIL.[36] after ransoms were paid.[35]
On 7 March, ISIL launched another massive attack on the villages around Tell Tamer, in an attempt to fully capture the area. Amid the fighting, there were fears that ISIL militants would use the kidnapped Assyrians as human shields.[37] The attack began around dawn and targeted at least three villages on the northern bank of the Khabur River, with ISIL's aim being to capture Tell Tamer and secure another corridor to the Iraqi border.[29] The next day, ISIL advanced close to the town and heavy fighting ensued, but Kurdish reinforcements arrived, and they managed to repel the militants. The clashes left 40 dead on both sides.[38] On 10 March, the YPG reported that their offensive in the eastern countryside of al-Hasakah had concluded successfully. However, on the same day, ISIL launched a surprise attack on Tell Khanzir, about 30 kilometers to the west ofRas al-Ayn, near the Turkish border in west Hasakah, capturing the town along with several other villages.[28][39] It was reported that ISIL had deployed hundreds[28] of battle-hardened Chechens from its Khorasan Battalion to carry out the assault.[19] Fierce clashes also erupted in and aroundManajir, a town to the northwest of Tell Tamer, as ISIL sought to strike northward. ISIL used the assault to prevent Kurdish forces in the east from reaching their stronghold ofal-Hawl, to the southeast, by occupying the Kurds on multiple fronts,[28] attempting to seize another border crossing with Turkey, and due to fears that the Kurds would use Ras al-Ayn as a base to seize control ofTell Abyad, and link theKobanî andJazira Cantons.[40] ISIL also wanted control of Ras al-Ayn and Tell Tamer to control additional key routes that would link the ISIL-held Iraqi city ofMosul with other ISIL-controlled territory in northeastern Syria.[40] On 12 March, the Kurds managed to repel the ISIL advance on Ras al-Ayn, resulting in dozens of casualties on both sides. However, ISIL advanced towards Tell Tamer and captured the village of Tal Nasri, bringing the militants to within 500 meters of the town. The fighting near Tell Tamer left 22 Kurdish and 18 jihadist fighters dead.[40]
Two days later, the Kurds recaptured the village of Tal Maghas, near Tell Tamer;[41] however, according to another report, ISIL managed to capture several more villages and crossed the Khabur River, in the area just northwest of Tell Tamer.[42][43] The YPG demanded more US-led Coalition airstrikes in the region, due to the fact that ISIL was deploying more reinforcements while the Coalition had not conducted any airstrikes near Tell Tamer since 10 March.[44][45] By this point, since the beginning of the ISIL counterattack on 10 March, the clashes in the Tell Tamer and Tell Khanzir areas had left at least 105 ISIL militants[19][46] and 63 YPG fighters dead.[19][47] On 13 March, the US-led Coalition resumed airstrikes in the region.[48]
On 16 March, the YPG advanced and captured some ISIL positions in the countryside around Tell Tamer.[49] The same day, 100Hezbollah fighters arrived in Ras al-Ayn from Qamishli to support Kurdish forces, according to the pro-opposition Al-Hasakah Youth Union, and were soon after sent to the battlefield where they were outfitted with Kurdish uniforms.[50] The next day, the IranianFars News Agency reported that the Syrian Army advanced and captured the town of Malaha, as well as its surrounding farm areas.[51] From 18 to 19 March, US-led Coalition airstrikes struck 3 ISIL tactical units, an ISIL fighting position, and an ISIL tunnel system in the area.[48]
On 20 March, more than 100 people were killed and wounded when an ISIL militant blew himself up at a celebration held by the Kurds for the festival of Nowruz, in the al-Mofti neighborhood of Al-Hasakah city, in addition to an IED explosion at another celebration in the city.[52]
Over the next several days, clashes erupted in the vicinity of Tell Khanzir, Tell Brak and Tell Tamer, killing dozens of ISIL militants,[19][53][54] while fighter jets bombed ISIL positions in the city ofAl-Shaddadi. Around this point, the offensive stalemated, as ISIL was unable to overrun Kurdish positions around the Tell Tamer and Manajir countrysides.[55]
Counteroffensive first phase – Tell Tamer countryside and Mount Abd al-Aziz
On 6 May 2015,[18] Kurdish forces launched a large-scale counteroffensive in the area ofTell Tamer to recapture territory they had previously lost to the Islamic State, and to push them out of the western al-Hasakah countryside.[6] Over the next three days, theYPG advanced in the Aalyah area, northwest of Tell Tamer,[56] and elsewhere,[57] while backed up by U.S.-led Coalition air-strikes.[58]
On the fourth day of the offensive, Kurdish Commander Rûbar Qamishlo, for whom the operation was named, was heavily wounded. Commander Qamishlo died of his wounds on 14 May.[10]
On 10 May, the YPG advanced on the road between Tell Tamer andAleppo.[59] On 11 May, the YPG advanced in the al-Salihiyyi area[60] and continued advancing northwest of Tell Tamer the following day,[61] eventually capturing the Alya area by 13 May.[62]
On 15 May, the YPG, backed up by the SyriacMFS andKhabour Guards, advanced in the Tal Hormoz area, amid continuing fighting and an ISIL car-bomb attack.[63] Two days later, the YPG captured parts of Tal Hormoz[64] amid mutual bombardment by both sides and an ISIL suicide car-bomb attack, while clashes also took place around Razaza village where Coalition air-strikes took place.[65]
On 18 May, the YPG-led forces captured two villages overlooking the road towardsMount Abdulaziz, a mountain range to the south of the Tell Tamer countryside.[66] On the following day, the YPG captured another three villages on the road heading towards the mountain, as ISIL hit them with two suicide car-bombs.[67] In all, between 17 and 19 May, the YPG captured about 20 villages.[68]
On 20 May, the YPG and allied forces captured wide parts of the mountain.[69] In addition, on 21 May, they seized the village of Aghaybesh, located on the road betweenQamishli and Aleppo.[70]
On 21 May, Kurdish forces captured the Assyrian villages of Tal Shamira and Tal Nasri, as well as two other villages.[71] Thus, they completed the first stage[18] of their two-week offensive successfully, recapturing Christian villages thatISIL militantstook control of three months earlier and seizing Mount Abd al-Aziz.[6]
Counteroffensive second phase – Ras al-Ayn countryside
On 26 May, the YPG captured the town ofMabrouka,[18] in the border area ofRas al-Ayn, bringing them closer to the ISIL-held border town ofTell Abyad,[3] then a major transit point for ISIL black-market oil commerce and foreign fighters from Turkey.[72]
In all, since 6 May, the YPG and allied forces captured 4,000 square kilometers of territory throughout the western Al-Hasakah Governorate,[3] including 230 towns, villages and farmlands.[8]
After the capture of Mabrouka, the YPG launched attacks on ISIL-held villages on the border. The Kurds claimed that 184 ISIL fighters were killed between 25 and 28 May.[21]
On 29 May, the YPG captured the entire countryside of Ras al-Ayn,[7] as they continued the second phase of their campaign.[73] Later that day, clashes on the administrative boundary between Al-Hasakah and Raqqa provinces took place that left 30 civilians dead at Nis Tal, on the Syrian–Turkish border, according to SOHR.[74] In contrast, Kurdish sources claimed nearly 100 people were massacred.[23] The civilians were killed by ISIL while trying to escape an advance by the jihadists. Meanwhile, the Kurds executed 20 civilians on the charges of supporting ISIL and burned and demolished homes of suspected ISIL supporters near Tell Tamer and Ras al-Ayn.[22]
On 31 May 2015, Kurdish forces pushed beyond the provincial boundary between the Al-Hasakah andRaqqa Governorates, thus ending the offensive operations within the western Al-Hasakah Governorate.[2]

On 30 May, ISIL launched an offensive towards the Syrian government-controlled part of Al-Hasakah, and advanced in the city's outskirts after two suicide bombers targeted Syrian Army positions, killing and wounding 50 soldiers.[75] The offensive originated from the ISIL-held town ofAl-Shaddadah, south of Al-Hasakah,[76] and was the jihadist organizations's third assault on the city in 2015.[77] On 31 May, Kurdish forces seized four villages on the provincial boundary between Al-Hasakah andRaqqa. The SOHR also reported that clashes were continuing between YPG and ISIL forces to the southwest of Ras al-Ayn.[2]
On 8 June, the ISIL offensive ended in failure, and they withdrew.[78][77]
On 23 June 2015, ISIL launcheda full-scale offensive to seize control of al-Hasakah city, storming the Syrian Government-held southern districts of the city.[79][80] On 1 August 2015, following more than 5 weeks of large-scale urban warfare, and heavy intervention by the YPG and the US-led Coalition, the Kurdish-led forces and the Syrian Government fully expelled the Islamic State from al-Hasakah city and its surrounding countryside,[81][82]
On 15 July 2015, an ISIL militant attempted to carry out a suicide attack in the area betweenTell Brak andal-Hawl; however, he was captured by the YPG, and the explosives were disarmed.[83]
On 17 July, three ISIL militants attacked the village of Nestal, to the west of the town of Mabrouka. One of the militants was reportedly killed, while another fled across the border into Turkey.[84]
On 8 August 2015, ISIL militants carried out an attack on the village of Abu Hamal, to the south of Tell Hamis. The YPG and YPJ counterattacked, forcing ISIL to withdraw from the region.[85]
On 10 October 2015, the YPG and their Arab allies merged into a single organization, theSyrian Democratic Forces (SDF).[86] Subsequently, the SDF went on to launch further offensives on ISIL's last 2 al-Hasakah Governorate strongholds ofal-Hawl andAl-Shaddadi, with the SDF taking al-Hawl and the surrounding area by 30 November 2015,[87][88] and taking al-Shaddadi and its countryside by 24 February 2016.[89][90] Towards the end of the offensive on Al-Shaddadi, on 22 February 2016, the Islamic State released the last 42 survivors of their 400 Assyrian Christian hostages, after they had spent nearly a year in captivity.[91]
