Iraq urged a U.S.-led military coalition on Sunday to use air power to protect the country's antiquities from Islamic State fighters looting and destroying some of the world's greatest archaeological treasures.

A government minister said the coalition, which has carried out 2,800 airstrikes against Islamic State military positions in Iraq and Syria since August, was not doing enough to save Iraq's priceless heritage.

The ultra-radical militants attacked the 2,000-year-old city of Hatra in northern Iraq on Saturday with bulldozers, officials say, days after assaulting the ancient Assyrian city of Nimrud.
