A Ukrainian special-forces captain identified as Serhii K. began a war crimes trial in Hamburg on Wednesday, accused of commanding a sabotage team that destroyed three Nord Stream pipelines in September 2022. German prosecutors allege the operation was ordered by Ukrainian state agencies to cut off Russian gas revenues, charging the defendant with sabotage and the deliberate attack on civilian infrastructure. The defense argues that the pipelines constituted a legitimate military target in Ukraine’s war of self-defense and that the defendant’s extradition from Italy was irregular because war crimes charges were added after his transfer. Serhii K. has refused to speak, and his attorneys contend that Ukrainian law binds him to confidentiality regarding his service, preventing him from fully defending himself.

Background

German prosecutors state that forensic evidence links other members of the alleged sabotage group to the attack, though no direct physical evidence ties Serhii K. to the scene.
A December ruling by Germany’s Federal Court of Justice rejected the argument that civilian infrastructure becomes a valid military target solely because its revenues finance a war, establishing legal hurdles for the defense.
Another suspected diver, Volodymyr Zh., was arrested in Croatia and faces potential extradition to Germany, where explosive traces found on his equipment reportedly match those at the blast sites.
Ukrainian President Volodymyr Zelensky has denied official state involvement in the attack, while Kyiv has provided only consular assistance to the defendant, whose defense is reportedly funded privately.
