The US-backed Syrian Democratic Forces (SDF) yesterday announced that they had regained full control of the Al-Sina’a Prison, six days after Daesh militants attacked the prison to free thousands of the group’s fighters.

“The Peoples’ Hammer Operation has culminated with our entire control of the Al-Sina’a Prison in Al-Hasakah and the surrender of all Daesh terrorists,” SDF spokesman Farhad Shami said in a message posted online.

The UK-based Syrian Observatory for Human Rights also reported that fighting inside and around the prison led to the death of Daesh militants, 50 Kurdish fighters and seven civilians.

On 20 January, about 200 Daesh fighters stormed the prison in an effort to release detained members of the group.

The ISIS attack is the “largest and most violent” since the SDF declared that it had defeated the terror group’s self-proclaimed “caliphate” in March 2019.
