Clinton accuses Russia over Syria
The US Secretary of State says Russian policy will contribute to a potential civil war in Syria.
Hillary Clinton's comments came after Russia and China renewed opposition to tougher UN Security Council action.
UN Secretary General Ban Ki-moon has repeated a warning that Syria could be moving towards "catastrophic" civil war, in the wake of the Houla massacre.
Rebel commanders are meanwhile split on whether abandon a ceasefire if Syrian forces do not withdraw to barracks.
The FSA's Colonel Qassim Saadeddine in Homs said that if there was no government response by Friday lunchtime the FSA would consider itself "no longer bound" by the plan.
But the FSA head, General Riyad Asaad, later denied the deadline existed.
