DOHA, Qatar – The newly elected leader of Syria’s main opposition group slammed the international community for what he called inaction, saying Saturday that fighters are in desperate need of weapons to break the stalemate with President Bashar Assad’s forces.

George Sabra’s comments came as his Syrian National Council struggled with other opposition groups to try to forge a cohesive and more representative leadership as rebels step up attacks against regime forces.

Two suicide car bombers struck a military camp in the southern city of Daraa on Saturday, killing at least 20 government soldiers and prompting clashes in the area, activists said.
