Moscow has claimed that explosions at the Nord Stream 1 and 2 gas pipelines were caused by a UK navy unit.
It provided no evidence to support its claim.
Last month, at least 50 metres of the underwater pipeline that transports Russian gas to Europe were destroyed.
Danish police have said “powerful explosions” caused four holes in the pipelines.
German, Danish, and Swedish authorities have been investigating the incident but it is still not known who or what caused the blasts.
In a statement, Russia’s Defence Ministry said: “According to available information, representatives of this unit of the British Navy took part in the planning, provision and implementation of a terrorist attack in the Baltic Sea on September 26 of this year.”
Although Western leaders have not directly accused Russia of being behind the attack, the EU has previously said Moscow was using its gas supplies as a weapon against the West.
The war in Ukraine has put pressure on gas supplies, pushing up prices for many European countries.
