On May 3 morning, ISIS prisoners started a mutiny in the Geweran prison south of the city of al-Hasakah in northeast Syria.
The U.S.-backed Syrian Democratic Forces (SDF) quickly dispatched a large, well-armed force to restore order in the prison. Several sources reported that U.S.-led coalition warplanes were also observed flying over the prison, likely to monitor the situation.
In the afternoon, sources in the SDF told the Hawar News Agency (ANHA) that the mutiny ended, confirming that the prison is again under control. No casualties were reported.
3,000 to 5,000 ISIS terrorists are being held in the prison, which is being run by the SDF with support from the U.S.-led coalition.
Last March, the prisoners staged a similar mutiny and managed to take over parts of the prison for at least two days. Some reports claimed that few prisoners even manged to escape. However, these claims remain unverified.
ISIS foreign detainees in the prison may be worried of the SDF’s recent decision to hold trials over them in Syria. The group’s legal body is reportedly making preparations for the trials.
