State television reported that the army troops had seized full control of the al-Sakhour district in eastern Aleppo early on Monday, the 14th day into its latest offensive to drive the terrorists out of the city.
Demining operations were now underway there, the report added.
The so-called Syrian Observatory for Human Rights confirmed the development.
“It is the biggest defeat for the opposition in Aleppo since 2012,” said its director Rami Abdulrahman. “The opposition has lost more than third of the area it controlled in Aleppo city during the big advance,” he added, according to Press TV.
He said government forces had also recaptured the districts of Haydariya and Sheikh Khodr, while Kurdish forces took Sheikh Fares District from militants.
Abdulrahman further said some 10 Aleppo neighborhoods over the past few days have been retaken by Syrian soldiers, putting nearly 30 percent of the city’s formerly militant-held neighborhoods back under Damascus control.
A day earlier, the military had chased militants out of the neighborhoods of Jabal Badra, Baadeeen, Inzarat, al-Sakan al-Shaabi, Bastan al-Basha, Arz al-Hamra’, al-Halak, and Ain al-Tall in the city.
Over the weekend, Syrian forces also retook Masaken Hanano, the biggest district in eastern Aleppo.
The government holds and defends the city’s western side and is purging its east of militants.
Aleppo’s full recapture would deal a decisive blow to the foreign-backed militants, who have been in control of its eastern side since 2012.
