Malcolm Chalmers, research director at Royal United Services Institute (RUSI), says the use of chemical weapons in Syria would be a “game changer”.
“If indeed there is confirmation of chemical weapon use, then we would move much closer to some sort of American military intervention,” he said.
He added: “Both the regime and the rebels have said that chemical weapons have been used…
“Both the [US] President and the Secretary of State Clinton have made it clear that such use would be unacceptable and it would lead to unspecified consequences – but it’s pretty clear those consequences would be military.”
