Russian war planes killed at least 14 and wounded 20 other civilians on Monday in air strikes on Syrian opposition controlled parts of the Aleppo province.
Most of the dead and injured people were children; while also damaging a number of residential areas and a school.
Russian Federation also conducted air strikes on Aleppo’s opposition controlled Sukkari, al Hulk and Firdevs districts, local civil defence sources reported.
A member of a local coordination committee Mustafa Abu Shafik told media that Russian fighter jets conducted more than 70 air strikes in southern Aleppo.
The local coordination committee consists of local activists who are fighting against the Syrian regime.
Shafik said that forces loyal to the Bashar al Assad regime had retaken Aleppo’s southern village of Hilsa with support by Russian air strikes.
Shafik also said that opposition forces responded by conducting attacks on regime forces that were using the region as a military headquarter.
Russian Federation's first air strikes that were conducted to support the Assad regime started on September 30, saying that this was a bid against DAESH.
That time the US Defense Secretary Ash Carter said "I want to be careful about confirming information, but it does appear that they (Russian airstrikes) were in areas where there probably were not ISIL [DAESH] forces."
Russia recently increased the frequency of its air strikes not against DAESH but against opposition forces which are supported by western countries.
Regarding its air strikes, Russian war planes are also targeting civilians who are not involved with either the opposition fighters nor DAESH terrorists.
Human Rights Watch (HRW) also accused Russian warplanes of hitting civilian targets in western Syria, claiming dozens of innocent lives, adding that the act is considered a war crime.
Western countries are carrying out air strikes against DAESH, which spread in Syria and Iraq, named US-led Combined Joint Task Force, (CJTF) under Operation Inherent Resolve.
The Syrian civil war which started in 2011, has killed at least 250,000 people and up to ten million people have fled from their homes to different countries, according to the United Nations.
