This is reported by the Sky News channel, citing a source in the British Ministry of Defense.
According to the source, the mines could have been placed near gas pipelines with the help of an underwater drone.
He noted that this could have happened months or even years ago.
Press Secretary of the President of Russia Dmitry Peskov earlier recalled that in February, US President Joe Biden promised to get rid of Nord Stream 2.
According to Swedish Foreign Minister Ann Linde, the incidents with gas leakage occurred as a result of explosions.
The locations of physical damage to both Nord Stream lines have been identified and are located in the exclusive economic zone of Denmark and Sweden.
