German federal prosecutors have filed charges against a 50-year-old Ukrainian national over the 2022 explosions that severely damaged the Nord Stream gas pipelines, according to two reports from Al Jazeera. The suspect, identified only as Serhii K under German privacy rules, faces allegations including attacking civilian energy infrastructure, causing an explosion, and acting on behalf of Ukrainian state authorities. The federal prosecutor’s office declined to comment on the specifics of the indictment, which was filed at a regional court in Hamburg.

Coverage comparison

Al Jazeera reported that the charges were filed on Wednesday or Thursday, with one account citing a detention filing from December 2025 by the Federal Court of Justice. In that filing, prosecutors alleged that Serhii K helped coordinate a team that used a sailing yacht, the Andromeda, to place explosive devices on the pipelines near Denmark’s Bornholm Island in September 2022. He is suspected of acting as the on-board coordinator and team leader, not as a diver or bomb expert.

Another Al Jazeera report describes Serhii K as a former Ukrainian army officer accused of leading a team of divers, a ship captain, and an explosives expert into Germany on a forged Ukrainian passport in September 2022. The suspect has denied involvement in the attack, according to one of the reports.

The reports also note that federal prosecutors confirmed to the AFP news agency that Serhii K was the same suspect who was arrested in August 2025 in Italy and extradited to Germany. The Berlin law firm Menaker, which is representing the accused, has not provided details on the indictment.

Key claims

German prosecutors allege that Serhii K, a 50-year-old Ukrainian national, was involved in the 2022 Nord Stream pipeline explosions. This claim is carried in both Al Jazeera reports.
The suspect is accused of acting on behalf of Ukrainian state authorities, as reported by Al Jazeera. The suspect’s full name is Serhii Kuznietsov, according to one report.
The explosions damaged the Nord Stream 1 pipeline and disrupted public services, according to Al Jazeera. The Nord Stream 2 branch was also damaged before it entered service.
The suspect used a sailing yacht, the Andromeda, to place explosive devices on the pipelines, as stated in a December 2025 detention filing cited by Al Jazeera.
Ukrainian President Volodymyr Zelenskyy said he had not received full details of the indictment, according to Al Jazeera. The suspect claimed to have been a member of the Ukrainian armed forces and in Ukraine at the time of the incident.

Context

The Nord Stream blasts took place in September 2022, seven months after Russia launched its full-scale invasion of Ukraine. At the time of the alleged attack, Moscow had halted gas deliveries to Europe through Nord Stream 1, blaming Western sanctions and technical issues. Europe accused Russia of weaponising energy supplies. Russia and some Western countries described the attacks as sabotage.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
