"Russian and Syrian airforces have not been active in Aleppo for more than two weeks. At the same time, US' B-52N strategic strike aircrafts, as well as F/A-18 carrier bombers flying from the aircraft carrier Dwight D. Eisenhower, and Rafale-M, flying from France's Charles de Gaulle aircraft carrier, conduct strikes on Mosul daily," the statement said.
"Over the last 24 hours alone, the [US-led] coalition has carried out 25 sorties, conducting 21 bombing strikes in the city and suburbs," Konashenkov said.
The operation to retake Mosul from Daesh, a jihadist group outlawed in Russia and a number of other states, has been ongoing since October 17. More than 30,000 Iraqi and 4,000 Kurdish fighters are taking part in the offensive, backed by about 5,000 US troops and supported by US-led coalition airstrikes. Mosul has been occupied by Daesh since 2014.
