The ancient city of Babylon, first referenced in a clay tablet from the 23rd century BC, was designated a UNESCO World Heritage Site on Friday, after a vote that followed decades of lobbying by Iraq. The vote, at a UNESCO World Heritage Committee meeting in Azerbaijan's capital Baku, made the ancient Mesopotamian city on the Euphrates River the sixth world heritage site within the borders of a country known as a cradle of civilization.
