Deir ez-Zor Military Prison

The military prison in Deir ez-Zor, capital of Deir ez-Zor Governorate in eastern Syria, was a key detention facility in a region that became one of the most contested in the entire conflict. After ISIS captured Deir ez-Zor city in 2014, government forces maintained a besieged pocket including the military prison for over 1,100 days until Syrian Army forces broke the siege in September 2017. The prison and its detainees were held in one of the most extreme siege conditions of the entire war — simultaneously imprisoned by the Assad government and surrounded by ISIS.
