Russia has accused the UK's Royal Navy of carrying out the Nord Stream gas pipeline explosions.
In a statement, the Russian defence ministry accusing the UK's marine force of sabotaging the key pipeline offered no evidence for its claims.
The defence ministry in Moscow 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 this year - blowing up the Nord Stream 1 and Nord Stream 2 gas pipelines."
