Inside ship that will neutralise Syria's chemical weapons

Syria has promised to hand over its remaining stocks of chemical weapons ingredients by 27 April.

They are bound for the M/V Cape Ray, a specially adapted 35,000-tonne US cargo ship that will neutralise the chemicals at sea.

It will take on over 500 tonnes of dangerous chemicals, including about 20 tonnes of mustard gas, the only battle-ready chemical weapon in Syria's arsenal.
