UN split on Ossetia resolutions
The UN Security Council is deadlocked over the situation in Georgia with the US and Russia rejecting rival resolutions on the crisis.
Washington says it is prepared to veto a Russian resolution seeking to implement a six-point ceasefire plan.
Russia has reiterated its opposition to a rival French text, reaffirming Georgia's territorial integrity.
Most Russian soldiers are due to leave Georgia shortly but 500 will stay in a "buffer zone" around South Ossetia.
Russia has set itself a deadline of Friday night to pull back all its combat troops .
