Representatives from more than 100 countries are holding talks in Paris in a fresh attempt to decide what should be done to end the violence in Syria.

However, Russia and China - two of President Bashar al-Assad's most important allies - are not attending the Friends of Syria group meeting.

The meeting comes just days after world powers agreed a roadmap for a political transition in Syria.

The Paris meeting follows similar events in Tunis and Istanbul which demanded tougher action against the Assad regime.
