British Prime Minister David Cameron Thursday urged the UN Security Council to "ramp up" pressure" on Syria following the resignation of envoy Kofi Annan, dpa reported.
"Frankly it shows that the current process isn't working. The Annan plan - he has worked very hard at it, but it hasn't worked, because we've got this appalling bloodshed, we've got this slaughter," Cameron told Sky News.
"I think what we need to do is actually ramp things up. We need to pass resolutions at the United Nations to put further pressure on Syria," he said.
