Syrian government forces have reportedly liberated the entire neighborhoods in Old City of Aleppo as part of a large-scale military operation to flush foreign-backed Takfiri militants out of the strategic northwestern city.

The so-called Syrian Observatory for Human Rights said on Wednesday that Syrian soldiers had established complete control over the historic area after militants withdrew in the face of army advances overnight.

The Britain-based monitoring group noted that the Takfiri terrorists “were forced to withdraw from the Old City neighborhoods of Aleppo for fear of being besieged.”

The Observatory said the militants withdrew from the last parts of the Old City after Syrian army units, in cooperation with allied fighters, restored security to Agyul and Bab al-Hadid neighborhoods of Aleppo, located some 355 kilometers north of the capital, Damascus, late on Tuesday.

The Syrian forces also secured the safe departure of more than 200 civilians from the liberated areas, and captured a number of terrorists there.

Earlier on Tuesday, the Syrian army had liberated Karm al-Dada, al-Sha’ar, al-Marjeh and al-Sheikh Lutfi districts in Aleppo as well as Tallet al-Shurta hill east of Aleppo.

The Syrian army and allied fighters from popular defense groups are now in control of more than 75 percent of eastern Aleppo.
