Key Points
- First Public Trial: A 50-year-old Ukrainian military officer, Serhii Kuznetsov, has gone on trial in Hamburg, becoming the first suspect to face court over the September 2022 Nord Stream gas pipeline bombings.
- War Crime Charges: German prosecutors allege Kuznetsov ordered deep-sea divers and an explosives expert to attack civilian infrastructure, classifying the sabotage under Germany’s code of crimes against international law.
- Defense Motion to Dismiss: Defense attorney Nicola Canestrini argued the case should be dismissed, contending the pipeline was a “Russian weapon” and potentially a legitimate target, while highlighting that prosecutors lack direct DNA, fingerprint, or forensic evidence linking Kuznetsov.
- Secrecy and Alibi Restrictions: The defense maintains that as a soldier bound by military secrecy, Kuznetsov cannot mount a fair defense or disclose military alibis without violating state secrets laws.
- State Denials: Both Kuznetsov and the Ukrainian government deny any involvement, with Kyiv maintaining that Ukrainian state agencies had no role in the operation.
Germany Latest News (GLN) October 14, 2026 – A Ukrainian man has gone on trial in Hamburg accused of blowing up Russia’s Nord Stream gas pipelines to Germany, four years after one of the most dramatic acts of sabotage in modern European history. Prosecutors say Serhii Kuznetsov played a leading role in a team of saboteurs that destroyed the pipelines, accusing him of a war crime. His defense team has formally called for the case to be dismissed.
The case is highly sensitive in Germany, one of Ukraine’s closest allies since Russia launched its full-scale invasion in February 2022, seven months before the attacks took place. Extradited to Germany last year from Italy, Kuznetsov denies the charges, as does a second suspect who is fighting extradition from Croatia.
Kuznetsov became the first suspect to go on trial for the blasts on Wednesday morning, and a packed public gallery looked on as he entered the courtroom, appearing relaxed. He even smiled at times, including during initial exchanges where he spoke to confirm personal details such as his name and place of birth. He had previously only been identified by German prosecutors as Serhii K. and pictured with his face blurred, but a court spokeswoman confirmed that he had waived his anonymity.
Kuznetsov, 50, wore a pair of headphones and appeared to listen intently to a translation of proceedings in Ukrainian, as the prosecution read out the charges against him of ordering divers and an explosives expert to attack civilian infrastructure.
What Is The Strategy Of The Defense Team?
The defense outlined their case, telling the court that only circumstantial evidence had emerged in the four years since the Nord Stream blasts.
As reported by journalist Paul Adams of the BBC, Italian defense lawyer Nicola Canestrini stated outside the courtroom that “[Prosecutors] made a thorough investigation of four years. They did not find one single witness, they did not find no forensics, no DNA, no fingerprints – nothing!”
Canestrini and his colleagues argued that as a soldier the defendant was bound to secrecy, and therefore he could not have a fair trial as he was unable to defend himself.
As further reported by Paul Adams of the BBC, Canestrini questioned: “Let’s say he has an alibi, he was on another secret operation, how can you prove that if he’s [not able] to tell us as defense attorneys where he was and which witnesses we could summon?”
Moving to dismiss the charges inside the courtroom, as reported by journalist Miranda Bryant of The Guardian, Canestrini argued that the pipeline was a “Russian weapon” and therefore potentially a legitimate target. Canestrini asked: “Is it unlawful to destroy an aggressor’s infrastructure without harming any human beings?”
How Are German Prosecutors Classifying The Sabotage?
Prosecutors argue the case falls under Germany’s code of crimes against international law as a war crime, defining it as an “attack by military means against civilian objects”.
The defense team told the court that his extradition to Germany was fundamentally flawed, asserting that no mention had been made at the time of the initial extradition requests regarding the formal war crime allegation.
In the months after explosives destroyed three of the four gas pipelines in the Baltic Sea off the island of Bornholm on 26 September 2022, Western suspicion looked towards Moscow without directly apportioning blame. Russia had already shut off the flow of gas to Germany in Nord Stream 1 weeks before the attack, and Nord Stream 2 had never been turned on. Berlin had frozen the multi-billion dollar project shortly before the invasion, and there were reports of suspicious Russian naval movements before the blasts.
As investigators from Sweden, Denmark, and Germany tried to find out who carried out the attack, Russia’s Vladimir Putin accused the US and its UK allies, blaming “the Anglo-Saxons” — an allegation that Western powers firmly denied.
Eventually, after Denmark and Sweden shut down their inquiries, German prosecutors focused on a group of deep-sea divers who had rented a yacht called the Andromeda in the northern German port of Rostock. Investigators stated later that “traces of subsea explosives were found in the samples taken from the boat”.
Despite the strain on diplomatic relations with Kyiv, German prosecutors pressed ahead with the case. In January 2025, the German Federal Court of Justice ruled that the case fell within German territorial jurisdiction and prosecutors had a legal responsibility to act as it involved “undermining [Germany’s] internal security”.
Ukraine’s President Volodymyr Zelensky has always maintained that Ukraine had “nothing to do with [the Nord Stream blasts],” although in their indictment, German prosecutors allege the saboteurs conceived and executed the plot “acting by order of Ukrainian state agencies”.
Background Of The Nord Stream Sabotage Development
The Nord Stream 1 and Nord Stream 2 pipelines were designed to transport massive volumes of Russian natural gas directly to Germany via the Baltic Sea bed, bypassing traditional transit countries in Eastern Europe. For years, the energy link was a focal point of intense geopolitical debate, with Western allies warning that it deepened Western Europe’s strategic dependency on Russian energy exports.
Following Russia’s full-scale invasion of Ukraine in February 2022, Germany halted the certification of Nord Stream 2, and Moscow subsequently choked off supply through Nord Stream 1. On 26 September 2022, powerful underwater explosions ruptured three of the four pipeline conduits near Denmark’s Bornholm Island, releasing vast plumes of methane gas into the ocean. Initial international suspicion centered on potential state-backed covert operations.
Multi-national investigations proved complex. While Swedish and Danish authorities eventually concluded their investigations without filing charges, German federal authorities maintained a dedicated task force. Italian law enforcement arrested Serhii Kuznetsov under an international warrant in 2025 before his eventual extradition to Germany, bringing the long-running criminal investigation into a open court.
How This Development Can Affect European Alliances And Political Stability
The trial of Serhii Kuznetsov is poised to have significant legal, political, and strategic ramifications for multiple key stakeholders across Europe:
Impact on German-Ukrainian Relations
The public airing of evidence alleging involvement by Ukrainian military personnel risks placing unprecedented strain on Berlin’s relationship with Kyiv. While Chancellor Olaf Scholz’s government has provided extensive military and financial backing to Ukraine, domestic political pressure could surge. Opposition parties in Germany may leverage the trial to question further unconditioned aid, forcing the German leadership to walk a delicate line between supporting Ukraine’s defense against Russia and upholding domestic judicial accountability.
Impact on European Energy Security and Legal Precedents
Classifying the destruction of cross-border industrial assets as a war crime establishes a major legal precedent in international law. If the court rules that infrastructure owned by an aggressor nation can or cannot be classified as a legitimate military target during war, it will redefine legal protections surrounding critical national infrastructure in future global conflicts.
