On 17 April 2018, rebel groups in the eastern Qalamoun Mountains pocket, led by Jaysh al-Islam, reached a surrender agreement with the Syrian Army and Russia. The agreement came after 2 weeks of negotiations that began with a Syrian Army ultimatum on 3 April. Around 1,500 rebels handed over heavy weapons and equipment to the Syrian Army, and were evacuated by 124 buses in 4 convoys to Turkish-held areas in the northern Aleppo Governorate along with their families, totaling around 5,000 people. On 25 April, the last batch of rebels and their families left the eastern Qalamoun pocket, and the region came under full Syrian government control.
