Sectarian violence reported in Syrian city of Baniyas
Sectarian violence has erupted in northwestern Syria, where three consecutive days of killing by mostly Alawite forces have left hundreds of predominantly Sunni residents dead, opposition groups said Saturday.
"The regime attacked the town of Beyda and other neighboring areas from the sea with rockets before security forces and militias loyal to the regime entered the area and conducted mass executions," Free Syrian Army chief of staff Gen. Salim Idris said by phone from Antakya, Turkey.
