Syria wants 'guarantees' for troop pullout

Syria's government appears to be pulling back from a United Nations peace plan, saying it wants "written guarantees" that opposition fighters will lay down arms before it implements a troop pullback agreed by President Bashar al-Assad, a demand refused by the main rebel group.

Hours after the government's demand on Sunday, the leader of the rebel Free Syria Army said his group is committed to the peace plan but will give guarantees to the international community.
