German Prosecutors Charge Ukrainian Suspect Over Nord Stream Explosions

G

erman federal prosecutors have charged a 50-year-old Ukrainian national with helping coordinate the 2022 sabotage of the Nord Stream gas pipelines, marking the most significant legal step yet in one of Europe’s most consequential infrastructure attacks.

The suspect, identified only as Serhii K under German privacy laws, is accused of playing a leading role in the operation that destroyed the Nord Stream 1 and Nord Stream 2 pipelines beneath the Baltic Sea, severing a major route for Russian natural gas exports to Europe months after Moscow’s full-scale invasion of Ukraine.

Federal prosecutors filed the indictment on Wednesday but declined to comment on its specific contents.

According to German public broadcaster ARD, Serhii K faces charges of attacking civilian energy infrastructure, causing explosions and destroying critical infrastructure.

The charges stem from an investigation into the September 2022 underwater blasts near Denmark’s Bornholm Island, which severely damaged both pipelines and disrupted Russian gas supplies to Europe during an already escalating energy crisis.

Court documents from December 2025 allege that Serhii K coordinated a team that used the sailing yacht Andromeda to transport explosives to the pipelines. Prosecutors claim he acted as the team’s on-board coordinator and operational leader rather than serving as a diver or explosives specialist.

The Berlin-based law firm Menaker, which represents the accused, has not commented publicly on the indictment.

German prosecutors confirmed that Serhii K is the same individual arrested in Italy in August 2025 following a German arrest warrant. Italy’s highest court later approved his extradition to Germany, where he was transferred in November 2025 to face investigation.

At the time of his arrest, German authorities alleged that the suspect had used forged identity documents to charter the Andromeda in the northern German port of Rostock before the vessel departed on the mission that investigators believe culminated in the sabotage operation.

Serhii K has denied any involvement in the explosions. His defense has maintained that he was serving with the Ukrainian armed forces and was inside Ukraine when the attacks occurred. His lawyers have argued that, even if military service were established, he would be entitled to what they describe as “functional immunity” under international law.

Ukraine denies involvement as investigation continues

The Nord Stream explosions remain among the most politically sensitive investigations in Europe, given their impact on regional energy security and the absence of any formal attribution of responsibility nearly four years after the attack.

Ukraine has consistently denied any state involvement in the sabotage or knowledge of any plot targeting the pipelines.

Speaking at a news conference in Dublin on Wednesday, Volodymyr Zelenskyy said it was too early to comment on the German indictment because Kyiv had not officially received details of the case.

“We have not officially received any details; at least I have not seen them,” Zelenskyy said, adding that it was premature to draw conclusions.

The twin Nord Stream pipelines, running beneath the Baltic Sea from Russia to Germany, had been central to Russian gas exports to Europe before relations between Moscow and the West deteriorated sharply following Russia’s invasion of Ukraine in February 2022.

Although Nord Stream 2 had never entered commercial operation, both pipelines were rendered inoperable by the explosions, eliminating a key component of Europe’s energy infrastructure.

The investigation has involved authorities from Germany, Denmark and Sweden, with investigators examining evidence including vessel movements, explosive residue and maritime records.

The indictment represents the first formal criminal case brought by German prosecutors against an individual alleged to have participated directly in the sabotage. However, investigators have not publicly alleged that the Ukrainian government authorized or directed the operation.

The case is expected to proceed through Germany’s federal court system, where prosecutors will seek to prove that Serhii K coordinated the team responsible for carrying out one of the most significant attacks on critical energy infrastructure in recent European history.
