“We are aware of the reports that Turkey has accepted the delivery of the C-400. As president (Donald Trump. - RT ) stated at the G20 summit on the eve of a meeting with Erdogan, “this is a problem, there is no doubt about it,” the agency’s source said.

Earlier, the first components of the S-400 missiles were delivered to the military base in the province of Ankara.

Pentagon Acting Secretary Marc Esper said he would discuss by telephone with Turkish Minister of National Defense Hulusi Akar the delivery of Russian C-400 anti-aircraft missile systems to Turkey.

Expert Edward Lozansky, in an interview with NSN, estimated the likelihood of Washington imposing sanctions against third countries because of the C-400.
