German federal prosecutors have filed charges against a Ukrainian national over the Nord Stream pipeline blasts, German media outlets ARD, Sueddeutsche Zeitung and Zeit reported on Wednesday.
Federal prosecutors declined to comment.
The blowing up of the Nord Stream pipelines, which carried Russian gas to Europe, was a major flashpoint in tensions between Moscow and the West, and came months after Russia's war on Ukraine in February 2022.
Prosecutors accuse the Ukrainian national, known only as Serhii K (but also known as Serhiy Kuznetsov, a former special forces soldier), according to German privacy laws, of attacks on civilian energy infrastructure, causing an explosion and the destruction of structures, according to the ARD broadcaster.
The suspect was arrested in Italy's Rimini province on August 21, 2025, and transferred to Germany on November 27, 2025.
A German judge put the arrest warrant into effect the next day.
Disrupting relations, causing massive damage
Serhii K has denied involvement. His lawyer Nicola Canestrini has said he is confident his client will be acquitted at a trial in Germany.
The explosions severely damaged both Nord Stream pipelines on September 26, 2022 in the Baltic Sea area.
German prosecutors accuse Serhii K of coordinating the September 26, 2022, Nord Stream sabotage near Bornholm island.
The group allegedly used the rented sailing yacht Andromeda departing from Rostock port with forged documents to plant explosives.
Investigators found traces of explosives on the vessel linked to the Ukrainian suspect and his associates.
Powerful underwater explosions ruptured three of the four pipelines, causing massive methane leaks into the Baltic Sea waters.
The blasts caused huge environmental damage and triggered sharp rises in European energy prices that year.
