Germany has found traces of underwater explosives in samples taken from a yacht suspected to have been used to transport explosives to carry out blasts on the Nord Stream 1 and 2 gas pipelines, the country writes this in a joint letter with Sweden and Denmark to the UN Security Council.

The three countries are each conducting their own investigations into who carried out sabotage on the gas pipelines in September last year.

They have sent a status report on the investigation to the UN Security Council on Tuesday – the day before a meeting of the council called by Russia.

Russia has complained that it has not been informed about the investigations.

”None of the investigations has been concluded and at this point, it is still not possible to say when they will be concluded. The nature of the acts of sabotage is unprecedented and the investigations are complex,” the three countries write in a joint letter dated Monday.

The letter contains updates on the investigations of all three countries.

The letter states that Germany has investigated ”the suspicious charter of a sailing yacht” that had been leased in a way that ”hide the identity of the real charterer.”

Germany is still investigating the vessel’s exact route.

”It is suspected that the boat in question may have been used to transport the explosives that exploded at the Nord Stream 1 and Nord Stream 2 pipelines,” reads the letter on Germany’s investigation.

”Traces of subsea explosives were found in the samples taken from the boat during the investigation.”

”According to expert assessments, it is possible that trained divers could have attached explosives at the points where damage occurred to the Nord Stream 1 and Nord Stream 2 gas pipelines, which are laid on the seabed at a depth of approx. 70 to 80 meters,” it adds.

Russia says the West is behind the blasts. However, Western governments have denied any involvement. So has Ukraine, which Russia invaded in February last year.

In March this year, Russia tried unsuccessfully to get the UN Security Council to ask for an independent investigation into the Nord Stream explosions.

”At this point it is not possible to reliably establish the identity of the perpetrators and their motives, particularly regarding the question of whether the incident was steered by a state or state actor,” reads the letter concerning Germany’s investigation.

Nord Stream 1 and 2 are gas pipelines running from Russia to Germany.
