MOSCOW, November 1. /TASS/. The participation of British specialists in the attacks on the Black Sea Fleet and the Nord Stream gas pipelines will not go unretaliated, Russian Presidential Spokesman Dmitry Peskov told the media on Tuesday.

"Such actions cannot be left unnoticed just like that. Of course, we will consider further steps. It is impossible to act otherwise," Peskov stressed.

The Kremlin spokesman noted that Russian special services had evidence indicating that the guidance and coordination of the attack on Sevastopol Harbor was carried out by British military advisers.

"There is evidence that Britain was involved in this act of sabotage, in plain language, a terrorist act, against a vital energy infrastructure, and not Russian - it is very important to take this into account - but an international energy infrastructure," he added.

Peskov stressed that all information about British specialists’ participation in the attacks should be analyzed very closely by all.

"We expect that, despite the admissible silence of the European capitals, such analysis will eventually be carried out," Peskov said.

While answering the question whether Moscow would take the case to the UN Security Council, Peskov drew attention to the fact that it was necessary to systematize the available data first.

"This is a very sensitive matter, I mean, the methodology of collecting such information. What should be done in this situation will be done," he stated.

Earlier, the Russian Defense Ministry said that on October 29 the Kiev regime, with the participation of British specialists, carried out a terrorist attack on naval ships of the Black Sea Fleet and civilian ships in Sevastopol with nine drones and seven autonomous marine unmanned vehicles. All of them were destroyed. Also on Saturday, the Russian Defense Ministry accused British naval specialists of involvement in the explosions of the Nord Stream and Nord Stream 2 gas pipelines in September. The British Defense Ministry disclaimed the responsibility for Nord Stream explosions, calling Moscow's charges an "invented story."
