British and French Foreign Ministers are today heading to New York to press for a United Nations resolution aimed at halting the violence.
British Foreign Secretary William Hague and French Foreign Minister Alain Juppe said they will attend UN talks scheduled for Tuesday.
Officials hope Qatari Prime Minister Hamad bin Jassim and Arab League officials can persuade Russia and China to back a UN Security Council resolution.
Russia says it will not support any resolution which could enable foreign military intervention.
