Overview
- The German federal prosecutor announced on Thursday that investigators have formally accused Ukrainian authorities of ordering the September 2022 Nord Stream pipeline sabotage and have indicted a first suspect, identified as Serhii K.
- Prosecutors say the operation was carried out by a team of divers, a skipper and an explosives expert who rented a sailboat in Germany, sailed to the Danish island of Bornholm, attached explosive charges to Nord Stream 1 and 2, and detonated them.
- The accused was arrested in Italy on August 21, 2025, extradited to Germany in September 2025, and has said he was in Ukraine at the time while claiming to have been a Ukrainian army commander.
- Sweden and Denmark closed their probes in 2024 while Germany kept investigating, and the prosecutor’s public allegation now frames an official theory that will be tested in court as Ukraine continues to deny responsibility.
- The pipelines once supplied a large share of Germany’s gas, so the accusation revives questions about Europe’s prior dependence on Russian energy and could produce diplomatic, legal and energy‑security consequences if the case proceeds.
