Chemical weapons inspectors collect samples from Syria site

Chemical weapons inspectors have collected samples from Syria's Douma, two weeks after a suspected gas attack prompted retaliatory strikes by Western powers on the Syrian government's chemical facilities.

The site visit, confirmed by the Organisation for the Prohibition of Chemical Weapons (OPCW), would allow the agency to proceed with an independent investigation to determine what chemicals, if any, were used in the April 7 attack that medical workers said killed more than 40 people.
