Syrian government forces have retaken a second rebel-held district in eastern Aleppo, military sources say.
They say the army and its allies had “fully recaptured” Jabal Badro.
Hours earlier, rebel sources confirmed that neighbouring Hanano district had fallen and was now under government control.
Hundreds of civilians have been fleeing into the government-controlled areas of Aleppo as troops make advances into the east of the city.
The Syrian army’s offensive to retake eastern Aleppo – home to some 275,000 people – is now into its 13th day.
The assault has killed 219 civilians, including 27 children, the UK-based Syrian Observatory for Human Rights says.
Syrian state media quoted unnamed military sources as saying that Jabal Badro, which lies immediate south of Hanano, had been fully recaptured.
There has been no confirmation of this from the rebel side.
Hanano was the first neighbourhood in Aleppo taken by rebels in 2012, and its return to government control on Saturday is the Syrian army’s biggest success of its offensive so far.
Retaking all of the place would be a major victory for Syrian President Bashar al-Assad after five years of conflict.
