Polish Prime Minister Mateusz Morawiecki is convinced that Russia is behind the sabotage of the Nord Stream 1 and Nord Stream 2 gas pipelines. He said this when he arrived at the summit of the European Political Community in Prague on Thursday.

 "Most likely, according to the information we also receive from our foreign friends, this is the work of the Russian services," the head of the Polish government said.

 He emphasized that the Russian Federation's proposal a few days ago to release gas through an undamaged Nord Stream-2 thread only confirms the guilt of the Russian services.

 "Obviously, we will talk about this here today and tomorrow. This shows that here and now the EU and all of Europe must be united in connection with Russian blackmail," Moravetskyi said.
