Government troops were ordered to "carefully retreat" from the main areas of the city where the militants entered, the agency's interlocutors said.

The second video shows a fighter lowering the Syrian flag from the flagpole at the statue of Bassel al-Assad, the late brother of President Bashar al-Assad, on the eastern outskirts of the New Aleppo district.
The channel also transmits a message from militants who announced the seizure of a military research center on the outskirts of the city.
The groups control more than 40% of the western quarters of the city of Aleppo, Al Mayadeen TV channel reports.

The current escalation has become the largest since 2020 — then the parties agreed on a cease-fire with the mediation of Russia and Turkey, RBC reminds.
