Despite the continued bombardment by Syrian forces, the rebels have made strategic gains in the country’s north.
They have been entirely in control of the northern city of al-Raqqah since March.
But some citizens are worried about the future of their city as the opposition forces there remain divided and their rule over the area uncoordinated.
The latest public executions by a group that declared allegiance to al-Qaeda have only fuelled their fears.
