Dramatic images apparently released by members of the Islamic State confirm earlier reports that its members had severely vandalized Mosul’s Saint George’s Church, a site dating back to the 10th century. Previous accounts held that ISIS had fully razed the structure, known locally as Mar Gorgis. Instead, the damage appears limited to the facade and adornments of the originally Assyrian church. The site had been converted into a Catholic monastery in the 19th century and was being used as a makeshift prison by the militant group.
