MOSCOW, October 22. /TASS/. Moscow calls on the countries, having influence on the Syrian opposition, to observe their obligations to master the militants in Aleppo, spokeswoman of the Russian Foreign Ministry Maria Zakharova said on Saturday.

"Russia is working with UN in delivery of humanitarian assistance and evacuation of civilians, including children and those seeking medical help, from the seized districts of Aleppo," she told reporters. "This is hindered in all forms by militants of various terrorist units as they continue keeping civilians hostage."

"We are calling on all countries, having influence on the armed opposition and terrorists, to make everything to implement the undertaken obligations and master the militants," she said.

A humanitarian pause has been in effect in Aleppo since October 20, although the Russian and Syrian combat planes stropped delivering air strikes in the area of the city back on October 18. The ceasefire is effective from 08:00 to 19:00. The pause was initially extended to October 21 but news came on Friday evening that it will be in effect also on October 22. According to the UN data, there are about 8,000 moderate opposition fighters in Aleppo and also about 900 militants of Jabhat al-Nusra (a terrorist organization outlawed in Russia).
