Intense fighting between the SDF and ISIS continued for the fifth day in Syria’s northeastern city of al-Hasakeh on Monday, following ISIS’s biggest attack in Syria and Iraq in three years. In the evening of Jan. 20, as many as 200 ISIS militants, many wearing suicide belts, launched a coordinated multi-axis assault on al-Sina Prison, shortly after detonating two car bombs parked along the exterior walls of its northern wing. In the chaos that ensued, SDF vehicles were seized and used to break through secure walls, clearing the way for hundreds of ISIS detainees to escape.
