Russia is always going to be there for Assad at the UN, so that route is not likely to produce any results. The Guardian:
The head of the Arab League monitoring mission in Syria has said violence has risen significantly in the country in recent days, as the UN prepares to debate a resolution on the crisis next week. The flashpoint city of Homs has again been the focal point of clashes, which are thought to have killed at least 100 people since Wednesday. Activists in the besieged city reported a massacre had taken place at the hands of regime forces on Thursday. European and Arab states are frantically drafting a resolution aimed at ending the violence and seizing power from the president, Bashar al-Assad, whose regime had enjoyed absolute control over Syria until a sustained and increasingly violent challenge to its rule.
