According to the Russian center for Syrian reconciliation, the Syrian army gained control over 50 east Aleppo districts.
"The Syrian government fully controls 50 districts of eastern part of the city [Aleppo], which is about 70 percent of the territory previously controlled by militants."
A total of 66 militants have surrendered arms and left east Aleppo over the past 24 hours, the center said. They were granted amnesty by the Syrian government.
"Over the day, 66 militants have surrendered arms and left for the eastern parts of the city. They were granted amnesty, according to the decision by the Syrian president."
Over the weekend, the Syrian army backed by local militia liberated a number of districts in eastern Aleppo and is leading the offensive further after militants refused to surrender and leave the city peacefully.
Aleppo became major battleground in Syria over recent months, engaging government forces, terrorists and numerous opposition groups. Eastern Aleppo is currently encircled by government troops, and the fighting has affected thousands of civilians still trapped in the city. Previous internationally mediated ceasefires have collapsed as militants continued attacks and opposition failed to expel jihadists from the city.
