Russia`s defense ministry says two of its navy destroyers forced away a Dutch submarine to stop it spying on an aircraft carrier in the Mediterranean, BBC News reported.
The sub was 20 kilometers from the Admiral Kuznetsov aircraft carrier at the time of the incident, the military said, according to BBC News.
Russia sent a flotilla to the eastern Mediterranean ahead of an expected resumption of air strikes in Syria.
NATO said it was monitoring the ships in a ”measured and responsible way”.
An official said the Western military alliance would not go into details but said it had been observing the fleet for some weeks.
