Eastern Qalamoun offensive (September–October 2016)

The Eastern Qalamoun offensive was a large-scale military offensive against Syrian rebel positions in the eastern Qalamoun Mountains of the Rif Dimashq Governorate launched by the Islamic State of Iraq and the Levant along a frontline of more than 15 kilometers in the region.[5]

The offensive[edit]

On 3 September 2016, ISIL sent two car bombs towards rebel positions in the mountains, but both were destroyed before they could reach their targets. Following this, ISIL forces stormed the rebel-held territory from three different axes, overrunning several positions and reportedly killing more than 20 rebels.[8]


Three days later, an ISIL convoy was deployed as they launched a second assault in the area. During the clashes, the rebels destroyed an ISIL T-72, a bulldozer, and a ZU-23-2, the latter with a BGM-71 TOW missile.[10] The next day, Jaysh al-Islam recaptured a hill near Dumayr from ISIL.[11]


On 9 September, ISIL launched a third attack against rebel forces in the mountains. Rebels led by Jaysh al-Islam and various Free Syrian Army factions repelled the assault and dozens of ISIL fighters were killed.[9] Hundreds of rebel reinforcements reportedly arrived in the region the next day.[7] On 13 September, ISIL recaptured the three hilltops of Jabal Zubaydi, Tall Daba'a and Jabal al-Afa'i.[2] On 14–15 September, rebels launched a counter-attack to regain Jabal al-Afa'i.[12] On 17–18 September, ISIL forces launched a successful assault against rebel positions at Badiya, killing four and capturing forty defenders,[13] while losing two vehicles in return.[14] Heavy fighting between rebels and ISIL in the area was reported on 19 September, as the ISIL offensive entered its 3rd week.[15]


On 21 September, Ahrar al-Sham and the Forces of Martyr Ahmad al-Abdo recaptured the Rajem al-A'ali area, giving them the control of 40% of the al-Afa'i Mountains, while a Syrian Air Force MiG-23 targeting ISIL crashed in the region.[16][17] Rebel forces made further progress later that day, retaking several positions at Jebal Batra.[18] The pilot of the crashed government jet landed in rebel territory in the mountains and as a result of a truce in the area, the rebels handed him over to the Syrian Armed Forces and reportedly received small arms and ammunition from government forces in return.[1] By 23 September, the rebels were in control of 70% of Jabal al-Afa'i.[19]


On 26 September, unknown gunmen attempted to assassinate Harith Siwar, commander of Jaysh al-Islam in the Eastern Qalamoun Mountains.[3] On 29 September, ISIL forces launched a new attack in the eastern Qalamoun Mountains, leading to heavy clashes with the rebel defenders.[20] In the night of 1–2 October, ISIL fighters stormed eastern Jabal al-Afa'i amid heavy fighting with FSA forces.[21] Two days later, Jaysh al-Islam repelled another major ISIL attack on Jabal al-Afa'i and al-Naqab.[22] On 9 October, 12 ISIL fighters and an unknown number of rebels were killed in clashes after an attack by ISIL on al-Khandaq and al-Naqab mountain.[23] Five rebels were killed in clashes on the following day.[24] On 15 October, rebels launched an assault on Kahil Tes and Mahol areas.[25]
