"Since September 30, the Russian air group has carried out a total of 4,201 combat missions, including 145 sorties by strategic and long-range bombers," Lt. Gen. Sergey Rudskoy, chief of the Main Operational Directorate of the General Staff of the Russian Armed Forces, said in a statement.
Russia's jets conducted 18 airstrikes on terrorist units to aid the "Lions of the Desert" and "Kalamun" troops belonging to the Free Syrian Army.
Syria's opposition is also assisting Russian forces by providing coordinates of Daesh objects, Rudskoy noted.
"Constant contact is maintained with them [opposition fighters]. The opposition is providing Russia's aviation group command with coordinates of terrorist targets," Lt. Gen. said.
"The so-called Syrian opposition aids the success of the Syrian Armed Forces' ground operation. Currently there are over 150 such [joint] units in Syria," Rudskoy said.
Russian Armed Forces will work on uniting Syria's government forces and numerous fighting units all of which are battling Daesh terrorists, according to Lt. Gen. Sergey Rudskoy.
"I want to emphasize that we intend to continue to work towards uniting the efforts of government troops and other groups interested in liberating Syria from international terrorists," he said.
