Ancient Syria under threat from modern warfare

The civil war in Syria is doing more than tear a country's people apart - the nation's ancient relics and artefacts are also being destroyed.

Five of Syria's six world heritage sites - some built by the Roman Empire - have sustained some kind of damage over the past two years of fighting.

"All sides lose because this is a civil war. And this is the heritage and the identity, the background of the Syrian people," UNESCO's Anna Paolini told CNN's Ivan Watson.

A Syrian Rebel sent a video of a centuries old Christian book, written in Greek, to a CNN journalist. The book looks badly smoke damanged but the seller says the $2 million asking price would be spent on guns.
