Hamburg trial opens for Ukrainian accused in Nord Stream pipeline blasts
A Ukrainian man, Serhii Kuznetsov, went on trial in Hamburg on Oct. 14 over the 2022 explosions that damaged the Nord Stream gas pipelines. Prosecutors allege he led a six-person team that used a yacht to carry out the attack and accuse him of aiding a war crime by targeting civilian infrastructure. Kuznetsov denies involvement, as does Kyiv; the trial is expected to last until February.
The case concerns explosions in September 2022 that ruptured three of the four Nord Stream 1 and 2 lines beneath the Baltic Sea. The pipelines had carried, or were intended to carry, Russian gas to Germany. Prosecutors say Kuznetsov directed a six-person group operating from the yacht Andromeda, with divers placing the charges.
He was arrested near Rimini in August 2025 and sent to Germany. Another Ukrainian suspect, Volodymyr Zhuravliov, was held in Poland in September 2025; Poland declined extradition and freed him. He was later detained in Croatia in August 2026 and is awaiting extradition. Nord Stream 2 never entered service and had long been disputed over European energy dependence. Kuznetsov and Kyiv deny involvement.
The trial may shape public debate in Germany and Europe over how wartime attacks on energy infrastructure are judged. It could affect Ukrainian-German relations, the Ukrainian community in Germany, and legal cooperation across borders. Energy consumers may see renewed discussion of gas dependence and infrastructure security. The proceedings could also influence whether future sabotage cases are pursued through national courts, though the outcome remains uncertain.
