The Aleppo Media Center has uploaded drone footage on social media. The footage purports to show the complete destruction of Al-Shaar neighborhood in eastern Aleppo.
The video shows destroyed buildings that appear to be abandoned and streets filled with rubble in the area.
The city has been divided for years between the government-held west and rebel-held east. It has become the most intense front in the war.
In September, Syrian government forces launched a major Russian-backed assault on eastern Aleppo after their own siege. The United Nations says the area is home to 275,000 people.
