Rebel fighters work on an anti-aircraft weapon mounted on a pick-up truck after what they said was an offensive against them by forces loyal to Syria’s President Bashar al-Assad that attempted to advance in the village but failed to, in Ratian, north of Aleppo February 18, 2015. Battles in and around the Syrian city of Aleppo have killed at least 70 pro-government fighters and more than 80 insurgents after the army launched an offensive there, a monitoring group said on Wednesday.
