Timeline of Major Riots, Raids, and Escape Attempts in Heseke’s Sina’a Prison

, ,


The Sina’a prison is located the Ghweiran District of Heseke city. It is often called Ghweiran Prison for this reason. It is housed in buildings on the old campus of Al-Furat University. It is unclear exactly when the buildings stopped being used as educational facilities, but by the time they began to be used as a prison the area had already been used as military housing for years. The Sina’a Prison saw an influx of prisoners after the fall of Baghouz when ISIS’ lost the last of its territory. At that point, the SDF became responsible for thousands of ISIS-linked prisoners. Since then, the prison has housed between 3,000 and 5,000 inmates linked to ISIS at various times.

The Sina’a prison has a history of riots, and escape plans, though none have been successful until the coordinated attempt on January 20th. Below, we detail the incidents and raids that received the most extensive media coverage at the time they occurred. This is not an exhaustive list of the riots in the prison- as the facility was plagued with security issues, and guards often had difficulty entering certain cells. Importantly, in the months leading up to the attack in Heseke, HAT (internal security forces) discovered the plan and arrested many connected to it, as well as the chief planner.
