"The American teams sent a lot of warnings through the radio and loudspeaker, but the ships of the IRGC naval forces continued maneuvers at close range," RIA Novosti reported.
As specified, the crew of the Firebolt boat fired warning shots, as a result of which the Iranian ships retreated to a safe distance.
Earlier it was reported that the forces of the Black Sea Fleet are watching the US Coast Guard patrol ship Hamilton, which entered the Black Sea.
