BAGHDAD — Iraqi paramilitary forces said Wednesday that they have captured Hatra, a 2,000-year-old historical site near the northern city of Mosul, where U.S.-backed forces have been battling the Islamic State group for months.

The media arm of the state-sanctioned force made up mainly of Shiite militias broadcast images of the site Wednesday afternoon, showing what appeared to be the ancient ruins in the distance as militia vehicles drove through open desert. It was unclear from the video if the forces had actually secured the ancient site.

Karim al-Nouri, a spokesman for the paramilitary forces, told state TV they captured the UNESCO world heritage site and were around three kilometers (two miles) from a nearby town with the same name, without providing further details.

Iraqi forces often claim to have driven IS from areas that are still far from secure, or that quickly fall back into the militants’ hands.

Hatra is believed to have been built in the second or third century B.C. by the Seleucid Empire. IS militants destroyed it along with other major historical sites in and around Mosul after seizing much of northern Iraq in the summer of 2014. The extremist group believes antiquities promote idolatry, though it is also believed to sell artifacts on the black market to fund its operations.

In April 2015, IS released a video showed the extremists smashing sledgehammers into Hatra’s walls and firing assault rifles at priceless statues.
