Two Russian Navy vessels tracked the U.S. guided-missile destroyer Ross, which entered the Black Sea on Sunday, the Russian Defence Ministry said in a statement on Monday.
“The Vasily Bykov corvette and the Ivan Khurs reconnaissance ship of the Black Sea Fleet carried out direct control over the movements of the U.S. warship,’’ the statement said.
Coastal radar equipment of the Black Sea Fleet was used to keep the U.S. destroyer under constant surveillance, it said.
Five warships of the North Atlantic Treaty Organisation (NATO) took part in an annual Romania-led naval exercise Sea Shield 2019 in the Black Sea, which ended on Saturday.
The group visited Odessa in Ukraine, Poti in Georgia and Constanta in Romania, NATO said in a statement.
In response, four Russian Navy surface ships and a submarine took part in military drills earlier in the Black Sea, the Russian Defence ministry has said.
