The Russian army on Saturday accused the UK of being "involved" in explosions on the Nord Stream gas pipelines, saying the same British military specialists had helped Ukraine plan a drone attack on Moscow's Black Sea Fleet, AFP reported.

"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 that blew up the Nord Stream 1 and Nord Stream 2 gas pipelines," Russia's defense ministry said in a statement.
