Nov. 19 (UPI) -- An alleged Russian spyship near British waters deployed lasers in order to impede Royal Air Force pilots attempting to monitor the ship, British Defense Secretary John Healey said.

The vessel named Yantar made its second known visit this year, north of Scotland and entered British waters in the last few weeks. Healey said officials were taking Russia's "deeply dangerous" maritime moves "extremely seriously."

On Wednesday, the British Defense Ministry confirmed the Royal Navy deployed a frigate ship and deployed aircraft to track the vessel's every move.

"During which the Yantar directed light lasers at our pilots," the ministry posted to social media.

The Defence Secretary @JohnHealey_MP this morning confirmed that a Russian spy ship - the Yantar - is on the edge of UK waters, north of Scotland, having entered the UK's wider waters over the last few weeks.
