Syrian opposition fighters Friday killed a relative of political security chief Rustom Ghazali, a key regime figure, on Friday in the southern province of Deraa, a watchdog said, as government warplanes and artillery pounded restive suburbs of Damascus. State television also reported the attack, without mentioning the family ties between Ghazali, a Sunni Muslim, and the three men. \"An armed terrorist group attacked a number of people at a petrol station near the village of Qarfa, which led to the killing of one and the wounding of another,\" Syria TV said, identifying the dead man as Hussam Ghazali. It said the victim\'s father Fayez was wounded, and Jalal Ghazali was abducted. According to the Syrian Revolution General Commission, Free Syrian Army rebels targeted a \"gathering of security forces and shabiha (militiamen) in the Ghazali complex before noon. Deraa native Ghazali, 59, has been political security chief since his predecessor and three other senior security heads were killed in a Damascus bombing in July 2012. Ghazali was the head of military intelligence in Lebanon from 2002 to 2005, when Syrian troops withdrew from its tiny neighbour after occupying it for three decades.
