PARIS (AP) - The leaders of Britain and France say the Syrian opposition needs more international support to resist a deadly government crackdown.

French President Nicolas Sarkozy says "we cannot bring about a Syrian revolution ... if the Syrian revolution does not make an effort to rally together and organize so that we can better help them."

British Prime Minister David Cameron, at Sarkozy's side after meetings Friday in Paris, said Britain and France are working "to see what more we can do" to help the Syrian opposition.

Cameron said Britain is sending food rations for 20,000 people in Syria.

Britain and France have pushed for international condemnation of the authoritarian rule of Syrian President Bashar Assad amid an uprising in which the U.N. says more than 5,400 people have been killed.
