Syrian activists say President Bashar Al-Assad's troops and the fighters of his regime's opposition, are fighting for control of key northern districts in Damascus. The Syrian Observatory for Human Rights says intense clashes are concentrated in the capital's neighborhoods of Jobar and Barzeh. A resident in the area says shelling overnight "shook apartments" and terrified people living in the neighborhoods, according to a report of the Associated Press. Clashes subsided by early Wednesday but sporadic gunfire is still being heard in contested areas of Damascus. Fighting also raged in other Syrian cities, including Homs, where the regime pounded positions of opposing fighters with artillery and carried out several airstrikes on the Baba Amr district, which the fighters have been trying to recapture from the troops for days.
