This was stated by the deputy head of the Russian Center for the Reconciliation of the Warring Parties (CPVS) in Syria, Rear Admiral Oleg Gurinov.
"On the part of the US-led so-called international anti-terrorist coalition, gross violations of deconfliction protocols and the bilateral Russian-American memorandum on flight safety continue," he said.
According to Gurinov, one example is the cases of targeting combat aircraft weapons systems on aircraft of the Russian Aerospace Forces. The corresponding precedents are recorded by the pilots of the Russian Aerospace Forces during scheduled flights.
Russian Foreign Minister Sergei Lavrov said earlier that Washington wants to be the sole sponsor of the Middle East settlement, although it has long lost its neutral status.
