Russian President Vladimir Putin sent out a stark message on Sunday, warning that the Russian Navy can track any enemy and open “an inevitable attack” if needed.

“We can locate any enemy underwater, above water, in the air, and if need be, carry out an inevitable attack against it,” Putin said during a speech in Saint Petersburg in honor of Navy Day.

Putin’s comment came weeks after a British warship passed near Crimea last month and angered Moscow.

Russia stated that its forces fired warning shots toward the British destroyer and dropped bombs in its way to expel it from the Crimea beaches annexed from Ukraine in 2014.
