The UK says the British and Norwegian militaries led a military operation to deter Russian submarines suspected of “malign activity” in the north Atlantic.
Defense Secretary John Healey said a frigate, planes and hundreds of personnel monitored a Russian attack sub and two spy submarines near undersea cables and pipelines north of the UK.
He said the Russian vessels eventually left after the operation that lasted more than a month.
Healey said his message to Russia was “we see your activity over our cables and our pipelines and you should know that any attempt to damage them will not be tolerated and will have serious consequences.”
