 German officials believe Ukraine destroyed Nord Stream. German investigators probing the attacks on the Nord Stream pipelines are increasingly convinced that the question is linked to Ukraine. Does Spiegel and state broadcaster ZDF reported? Those familiar with the probe consider the clues pointing to Ukraine to be particularly convincing, the ZDF broadcaster said, adding that there is no reliable evidence that would suggest Russia was responsible. Law enforcement agencies are still largely focused on the Andromeda sailing yacht. Western media has previously reported that the vessel was chartered by the alleged saboteurs who used it to plant explosives on the undersea pipelines. Traces of these explosions were reportedly found in the cabin of the yacht. According to the two outlets, investigators now believe the group that used the vessel was in Ukraine before and after the explosions in the Baltic Sea in late September 2022. This was confirmed by technical data which law enforcement officials were able to retrieve and evaluate reports say citing security sources. The Wall Street Journal previously reported that the yacht was chartered by a Ukrainian-owned Warsaw-based travel agency and moored at a Polish port before sailing near each of the locations where the explosions later occurred. Both German outlets said the alleged saboteurs likely used a fake Moldovan passport belonging to a certain Stefan Marku to rent the vessel. The real Stefan Marku, who was contacted by the Spiegel and ZDF, said he learned about the sabotage from the news and never left Moldova in September 2022. He also said that the passport in question expired in October of the same year and that he had burned it. The Nord Stream 1 and 2 pipelines built to deliver Russian natural gas to Germany were destroyed by underwater explosions off the Danish island of Bornholm in September 2022.
