Free Syrian Army fighters take cover as they exchange fire with regime forces in the Salaheddin neighbourhood of Syria's northern city of Aleppo on August 22, 2012. At least 12 people were killed in a raid on a district of Damascus, while fighter jets and artillery pummelled the city of Aleppo and rebels claimed seizing parts of a town on the Iraqi border, a watchdog said.
