She added that militants holding civilians hostage were preventing Russia and the UN from delivering aid to Aleppo's besieged areas and helping civilians leave the city.
"We are urging all countries who have influence on the armed opposition and terrorists to do everything to fulfill the obligations they have accepted," Zakharova said.
On October 20, Russia introduced the first humanitarian pause in Aleppo since the Syrian Army began a major offensive on the rebel-held eastern districts of the city in September. On Saturday, Russia indicated that it might further extend the humanitarian pause, which had already been prolonged for October 22, from 08:00 to 16:00 local time, depending on the developments on the ground.
