The head of the Russian Foreign Ministry's European Cooperation Department, Andrey Kelin, said that the presence of US warships in the Black Sea will lead to retaliation, RIA Novosti reported.
"From time to time, US vessels enter the Black Sea. Obviously, we do not appreciate it and, undoubtedly, this will lead to retaliatory measures," Andrei Kelin told the Russian state-run news agency.
On June 6th, a US Naval destroyer, the USS Porter, entered the Black Sea to conduct exercises with partner navies, according to a statement issued by the US 6th Fleet.
Kelin also noted that the USS Harry S. Truman aircraft carrier has recently been relocated from the Persian Gulf to the Mediterranean Sea. According to US Admiral Bret Batchelder, the move is meant to send a clear message to Moscow.
