Hezbollah and local militias took part in the offensive to recapture the village of Minyan which is located next to Al-Assad in late October.
"The army and militias have kicked the terrorists out of the Al-Assad district," the source said, adding that the militants could mine some houses and streets when retreating.
On October 28, armed radical factions led by al-Nusra militant group attempted to break the siege of the eastern Aleppo that had been encircled by government forces.
In the course of the offensive, terrorists managed to capture most of the Al-Assad district and advance toward a military academy of the same name located nearby. The Syrian army and militia repelled the attack on the academy.
This week Syrian troops supported by national militias have regained control of the “1070”district and other strategic positions in the city. During the first days of intense fights, over 500 terrorists were liquidated, the source said.
