The Syrian government now controls 93 percent of Aleppo, Russian news agencies cited the Russian Defense Ministry as saying on Saturday.
"People are leaving through humanitarian corridors in a continuous flow into the part of the city that is controlled by the Syrian government," Defense Ministry spokesman Igor Konashenkov said, according to Interfax. "A large part of Aleppo - 93 percent - is today controlled by the Syrian government."
Konashenkov added that after the removal of civilians was completed, Syrian government forces would continue to "liberate" eastern Aleppo.
Syrian army rushes forces to historic Palmyra in IS battle
The Syrian army said it has sent reinforcements to Palmyra, where Islamic State fighters have advanced to its outskirts in some of the heaviest fighting since the group lost the historic city earlier this year.
The group had taken over areas to the northwest and southeast of Palmyra, and clashes continued on Saturday, the army said in a statement on Saturday.
A rebel commander from the Jaish al-Mujahideen group based in the Aleppo countryside said the IS attack was forcing the Syrian government to divert troops from Aleppo, where the army and its allies are on the verge of a major victory against rebels.
