ISIS militants have begun dismantling the ancient archaeological site of Hatra in northern Iraq in their ongoing effort to eliminate the region of what they consider idolatrous imagery, Iraqi authorities said Saturday.

The militants have destroyed parts of Hatra, about 70 miles south of Mosul, and started to pilfer antiques from the city, Qais Hussein Rashid, deputy minister of tourism and antiquities, told NBC News. He called the attack "a new crime against the Iraqi civilization and humanity in general."
