Some 90,000 residents live in east Aleppo freed from militants, the Russian center for Syrian reconciliation said.
"By noon on November 29, the territory of the city where 90,000 residents of Aleppo live, has been fully freed from terrorists."
Over the past 24 hours, 507 terrorists have left Aleppo and laid down arms, the center said, adding that 484 fighters among local residents have been immediately granted amnesty.
On Tuesday, Syrian Army's General Command called on militants to lay down arms in accordance with an amnesty decree, to stop the bloodshed, bombing of residential areas as well attacks on civilians.
Over the recent months, Aleppo has been a major battleground in Syria, engaging government forces, jihadists, and numerous opposition groups. Eastern Aleppo is held by militants, encircled by government forces, and the fighting has affected thousands of civilians still trapped in the city.
Between 200,000 and 300,000 civilians are still held by terrorists in the eastern neighborhoods of Aleppo, according to Under-Secretary-General for Humanitarian Affairs and United Nations Emergency Relief Coordinator Stephen O’Brien.
