This was reported by RIA Novosti.

It is noted that the ambassador entered the building of the US Foreign Office at approximately 16:05 local time (23:05 Moscow time).

Earlier, Antonov was summoned to the US State Department after the incident with an American UAV over the Black Sea.

On March 14, the US European Command announced that a Russian Su-27 hit the propeller of an American MQ-9 drone over the Black Sea, after which the drone fell into international waters.

At the same time, the Russian Ministry of Defense reported that Russian fighters did not use airborne weapons and did not come into contact with a US drone over the Black Sea.

The ministry said that as a result of sharp maneuvering, the US drone went into uncontrolled flight with a loss of altitude and collided with the water surface.
