CAIRO: The Kurdish-led Syrian Democratic Forces said on Sunday that five of its members had been killed during an attack by Daesh militants on a checkpoint in eastern Syria’s Deir el-Zor on July 31. The Daesh claimed responsibility for the attack in a statement on Monday. The SDF was the main fighting force allied to the United States in Syria during fighting that defeated Daesh in 2019 after the group declared a caliphate across swathes of Syria and Iraq. The Daesh has been trying to stage a comeback in the Middle East, the West and Asia.
