Islamic extremists have bulldozed  to the ground a massive 2,900 year-old Assyrian structure in northern Iraq. “One of the tallest surviving structures from the ancient world has been totally destroyed by [Islamic] extremists at Nimrud, the former capital of Assyria, which was captured by Iraqi government forces on 13 November. The ziggurat, which was nearly 2,900 years old, was obliterated. Only the largest Egyptian pyramids are higher than Middle Eastern ziggurats and central American step pyramids.”
