British Prime Minister David Cameron said Thursday it was time for Syrian President Bashar al-Assad to go to prevent civil war in the country. "In terms of Syria, I would have a very clear message for Assad, which is it is time for him to go," Cameron told reporters in Kabul during his visit to Afghanistan. "It is time for transition in this regime... but if there isn't transition it's quite clear there is going to be civil war," he added. The UN Security Council is scheduled today to vote a new Syria draft resolution.
