Former Ukrainian officer stands trial in Germany over Nord Stream sabotage

Four years after a significant act of sabotage in European history, a Ukrainian man is set to go on trial in Hamburg for allegedly detonating Russia's Nord Stream gas pipelines in Germany. Serhii K, the Ukrainian identified by German prosecutors, is accused of collaborating with other Ukrainian military personnel to destroy the pipelines in an attempt to stop the flow of gas revenue to Russia.

The case is highly sensitive for Germany, considering it is one of Ukraine's closest allies since Russia's invasion in February 2022, occurring seven months before the attacks. Serhii K, who was extradited to Germany last year, is the first suspect to face trial for the blasts, while another suspect is challenging extradition from Croatia.

Western suspicions initially pointed towards Moscow, but Russia pointed fingers at the US and UK, which both denied involvement. German prosecutors pursued the case, and in January 2025, the German federal court ruled that it fell within their jurisdiction, as it involved undermining Germany's internal security. Although Ukraine maintains its innocence, German prosecutors accuse the saboteurs of acting under the orders of Ukrainian state agencies, classifying it as a war crime.

The trial highlights the differences in opinion between Kyiv and Berlin regarding the bombings, with Ukrainian parliament chair Oleksandr Merezhko acknowledging the legal proceedings, while still maintaining Ukraine's innocence.
