The leaders of Britain and France have pledged to help the Syrian opposition in its struggle against Bashar al-Assad's regime.
Following talks in Paris, French President Nicolas Sarkozy and British Prime Minister David Cameron urged anti-Assad forces to unite and organize themselves better.
Sarkozy also said conditions were not right for a foreign intervention in Syria.
Meanwhile, Syrian activists said troops continued to shell parts of the central city of Homs, with one opposition group saying the bombardment on February 17 was the heaviest since troops launched attacks on antigovernment strongholds 13 days ago.
