Syrian civilians flee the northern city of Aleppo during a lull in fighting between opposition forces and army troops on July 25, 2012. Battles raged through the night in several districts of Syria's second largest city to which the regime had rushed reinforcement, after rebels launched an all-out assault for control of the country's commercial hub on July 20. Arabic graffiti on the police station's entrance reads "Assad's Syria". AFP PHOTO / PIERRE TORRES
