This was reported by TASS. 

Also, the American Foreign Ministry announced the intention of the United States to support the investigations of explosions on gas pipelines by European countries.

Earlier, Russian President Vladimir Putin said that Nord Stream was blown up by someone who was interested in supplying Europe with Russian gas only through Ukraine.

On November 18, the Swedish security service reported that these investigations confirm the information that sabotage was the cause of the emergency at Nord Stream.

Russian Deputy Prime Minister Alexander Novak noted that Poland, the United States and Ukraine could be interested in accidents at the Nord Stream gas pipelines.

On September 26, sabotage occurred on two Russian export gas pipelines to Europe, Nord Stream and Nord Stream 2.
