The Islamic State of Iraq and Syria (ISIS) group began bulldozing the ancient Assyrian city of Nimrud in Iraq on Thursday, the government said, in the jihadists' latest attack on the country's historical heritage.
ISIS "assaulted the historic city of Nimrud and bulldozed it with heavy vehicles," the tourism and antiquities ministry said on an official Facebook page.
An Iraqi antiquities official confirmed the news, saying the destruction began after noon prayers on Thursday and that trucks that may have been used to haul away artefacts had also been spotted at the site.
"Until now, we do not know to what extent it was destroyed," the official said on condition of anonymity.
Nimrud, which was founded in the 13th century BC, lies on the Tigris around 30 kilometres (18 miles) southeast of Mosul, Iraq's second city and the main hub of IS in the country.
The destruction at Nimrud, one of the jewels of the Assyrian era, came a week after the jihadist group released a video showing militants armed with sledgehammersand jackhammers smashing priceless ancient artefacts at the Mosul museum.
That attack sparked widespread consternation and alarm, with some archaeologists and heritage experts comparing it to the 2001 demolition of the Bamiyan Buddhas in Afghanistan by the Taliban.
