Ukrainian Ex-Officer's Trial for Nord Stream Sabotage Begins in Germany
A Ukrainian former military officer is currently on trial in Germany, facing accusations of organizing the operation that led to the destruction of the Nord Stream gas pipelines in 2022. This incident significantly impacted Western Europe's access to Russian natural gas. The trial began on Wednesday at the Hamburg Higher Regional Court and is anticipated to continue into February of the following year.
The defendant, identified only as Serhii K. due to German privacy laws, is alleged to have led a group of Ukrainian operatives, which included divers and an explosives expert, in what prosecutors describe as one of the most significant acts of infrastructure sabotage in recent history. Serhii K. denies any involvement in the operation and is the sole individual facing trial in this case.
Serhii K. was apprehended in Italy in August 2025 and was extradited to Germany in November of the same year. Prosecutors claim that he collaborated with other military personnel to plan the sabotage on behalf of unidentified Ukrainian state entities. They allege that he entered Germany via Poland using a forged Ukrainian passport approximately three weeks prior to the attack.
The group reportedly utilized a sailboat rented in Rostock to reach a location near the Danish island of Bornholm, where they attached military-grade explosives equipped with timers to the pipelines situated on the seabed. German prosecutors argue that targeting civilian infrastructure in this manner constitutes a war crime.
Details of the Nord Stream Explosions
On September 26, 2022, Swedish seismologists recorded multiple explosions, occurring 17 hours apart, which resulted in the rupture of three out of four concrete-coated steel pipelines, releasing substantial amounts of methane into the atmosphere. Prior to the incident, Nord Stream 1 was responsible for supplying about half of Germany's natural gas imports, while Nord Stream 2, although constructed, was never operational due to Berlin's decision to halt its approval shortly before Russia's invasion of Ukraine.
Cleared to File
Russia has denied any involvement in the destruction of its own pipelines and had already reduced gas supplies in response to European sanctions. The Ukrainian government has also refuted any claims of its involvement in the sabotage. Recently, Russia expressed its expectation for a "just verdict" that would identify the perpetrators and those who ordered the operation.
Another individual, identified as Vladimir Z., a trained diver believed to have been part of the team, was arrested in Croatia in August. A Croatian court has since approved his extradition to Germany, further complicating the legal proceedings surrounding the Nord Stream case, which has already strained relations between Berlin and Kyiv, despite Germany's strong support for Ukraine amid ongoing hostilities with Russia.
