DAMASCUS, June 29 (Xinhua) -- Islamic State (IS) prisoners rioted in a prison run by the Kurdish-led Syrian Democratic Forces (SDF) in the northeastern Syrian province of Hasakah on Monday, a war monitor reported.
The IS prisoners staged the riot in the Ghweiran prison in Hasakah, demanding "fair trials" and allowing visits by their families, said the Syrian Observatory for Human Rights.
The UK-based watchdog group said the IS members tried to destroy the walls and gates of the prison amid confirmed information of casualties among the prisoners.
In tandem with the riot, helicopters of the U.S.-led anti-terror coalition flew on a low altitude in Hasakah.
The IS prisoners staged a similar riot on May 3, which ended after hours of negotiations between the prisoners and the U.S.-backed SDF.
The SDF runs prisons in areas it controls in northeastern Syria, where around 10,000 IS members are imprisoned, 2,000 of whom are foreigners.
The North Press Agency, a media outlet running in Kurdish areas in northeastern Syria, said dozens of SDF members arrived in the vicinity of the prison in Hasakah. It added that the SDF closed the roads leading to the prison. Enditem
