The prison is located in the town of Al-Hawl in Hasakah's eastern suburbs, according to the Sana news agency.

Several low-level IS members escaped another Kurdish-controlled prison, al-Sinaa, in Hasakah in late March. They reportedly used a ripped-off door to break down a wall before fleeing, Sputnik reported.

Earlier this month, the Syrian Arab News Agency has reported, citing local sources, that a major insurrection by IS prisoners had taken place at the al-Sinaa prison facility in the US-backed SDF-controlled area in Hasakah, northeast Syria.

The al-Sinaa prison contains IS fighters of various nationalities, and is run by the SDF under the supervision of US occupation forces, holding part of the estimated 10,000 ex-IS fighters that the SDF has in its custody.

20 percent of these 10,000 prisoners are said to consist of foreigners whose home countries have refused to repatriate them.
