David Cameron Says There is "Limited But Growing" Evidence Syrian Forces Used Chemical Weapons
Calls the move a war crime
There is "limited but growing" evidence that Syrian government troops have used chemical weapons, UK Prime Minister David Cameron says.
"It is extremely serious, this is a war crime," Mr Cameron told the BBC.
On Thursday, the White House said that US intelligence agencies believed "with varying degrees of confidence" that Syria had used the nerve agent sarin.
