UNITED NATIONS (AP) -- Security Council ambassadors are gathering Saturday morning to consider a draft resolution backing an Arab League call for Syrian President Bashar Assad to step down.
The unusual weekend session comes as Syrian forces pummel the city of Homs with mortars and artillery in what activists are calling one of the bloodiest episodes of the uprising.
Although Western nations are pressing for a vote, there's no guarantee the resolution will pass.
Russian Foreign Minister Sergey Lavrov is saying at a security conference in Munich that Moscow still sees two problems of "crucial importance" with the draft resolution on the violence in Syria. Western countries have been working to head off a possible Russian veto if the resolution goes to a vote.
