World leaders meeting for the final day of the G20 summit in Russia remain divided over military action in Syria.

Italian PM Enrico Letta said the splits in opinion were confirmed at Thursday's working dinner in St Petersburg.

A spokesman for the Russian presidency said a US military strike on Syria would "drive another nail into the coffin of international law".

At the UN, the US ambassador accused Russia of holding the Security Council hostage by blocking resolutions.
