An image grab taken from a video shows opposition fighter holding a rocket propelled grenade (RPG) as his fellow comrades take cover from an attack by regime forces on August 26, 2013 during clashes over the strategic area of Khanasser, situated on the only road linking Aleppo to central Syria. Rebels had in recent days captured several villages in Aleppo province, much of which is already in the hands of anti-regime fighters, before taking Khanasser, situated on the highway to Hama in central Syria, thus cutting the army’s only supply route to the northern province.
