Italy Extradites Ukrainian Nord Stream Suspect to Germany

Italian Court Clears Extradition

Italy's highest court, the Supreme Court, approved the extradition of Ukrainian national Serhii Kuznetsov to Germany, where he is suspected of involvement in the 2022 Nord Stream pipeline explosions. The ruling, which rejected a final defense appeal, was made on November 19, 2025. Kuznetsov was subsequently transported to Germany by helicopter on November 27, 2025, under the supervision of German authorities.

Allegations and Arrest

German prosecutors accuse Serhii Kuznetsov, identified as Serhii K. under German privacy laws, of coordinating a group that planted explosive devices on the Nord Stream 1 and Nord Stream 2 pipelines. The explosions, which occurred in the Baltic Sea near the Danish island of Bornholm in September 2022, severely damaged three of the four pipeline strings, disrupting Russian gas transit to Europe. Kuznetsov, a 49-year-old former soldier, was arrested on a European arrest warrant in August 2025 near Rimini, Italy, while on vacation with his family. He faces charges including collusion to cause an explosion, anti-constitutional sabotage, and destruction of important structures.

Defense and Broader Investigation

Kuznetsov has consistently denied any role in the attacks, stating he was serving as an army captain in Ukraine at the time of the blasts. His lawyer, Nicola Canestrini, has expressed confidence that his client will be acquitted during a trial in Germany. During his detention in Italy, Kuznetsov reportedly went on hunger strike due to alleged mistreatment.

The investigation into the Nord Stream sabotage has been complex and international. While investigations in Sweden and Denmark have concluded without charges, Germany continues its probe. The case has also seen other developments, including the arrest of another Ukrainian citizen, Volodymyr Z., in Poland. However, a Polish court subsequently blocked his extradition to Germany, citing national interests.

Next Steps in Germany

Following his arrival in Germany, Kuznetsov is expected to appear before an investigating judge of the Federal Court of Justice in Karlsruhe, who will likely issue an arrest warrant. He will then stand trial in Germany, with Hamburg reportedly under consideration as the venue.
