The Islamic State group demolished a prison in the ancient Syrian city of Palmyra Saturday, a monitor said, destroying what was for decades one of the regime’s most feared detention centres.
The prison was “largely destroyed after IS planted explosives inside and around it” 10 days after the jihadists seized Palmyra from government forces, the Syrian Observatory for Human Rights said.
