Destroying Syria's chemical weapons at sea

A ship in the middle of the Mediterranean has started the delicate task of destroying 600 tons of Syria's chemical weapons. The Cape Ray, a former container ship, has been refitted to become the first seaborne vessel capable of decommissioning toxic materials on the high seas. Michael Luhan, spokesperson for the Organisation for the Prohibition of Chemical Weapons, explains this challenging, unprecedented mission involving more than 30 countries.
