Syrian troops shelled several districts in Aleppo and clashed with opposition forces on Tuesday (September 18th) in Bustan al-Qasr in the southwest and in nearby Izaa, AFP reported.
Two civilians were killed overnight during shelling of the rebel-held Sakhur neighbourhood in the northeast, while nearby Hanano was also bombed, the Syrian Observatory for Human Rights said.
Syrian forces said they had secured the Midan district on Monday after a week of fighting.
Pro-regime newspaper Al-Watan said the army had "cleansed" Midan, which "opens the door" to nearby neighbourhoods, including Bustan al-Basha, Suleiman al-Halabi and Sakhur.
But the two-month-old battle for Aleppo was still very fluid, Observatory director Rami Abdel Rahman said.
In Aleppo province, two civilians were killed in shelling on the town of al-Bab and the town of al-Safira was also reportedly bombed, according to the observatory.
The violence followed a bloody day Monday in which 137 people -72 civilians, 24 rebels and 41 soldiers- were killed nationwide, the Observatory said.
The Britain-based group said more than 27,000 people have been killed since the uprising erupted in March 2011. The United Nations puts the toll at over 20,000.
