The Islamic State of Iraq and Syria (ISIS) has released a new video showing what appears to be the terror group's destruction of an ancient city in Iraq.

It was a city that stood for 3,000 years, reduced to dust in a matter of seconds. That's what new video from ISIS purports to show. It cannot be independently verified.

But if legitimate, a crater is all that remains of the ancient Assyrian city of Nimrud, one of Iraq's greatest archaeological treasures.
