German trial of Ukrainian suspect exposes tensions in Kyiv support amid Nord Stream charges

Full analysis

On October 14, 2026, the Hanseatic Higher Regional Court in Hamburg opened the trial of Sergiy Kuznietsov, a 50-year-old Ukrainian former military officer and father of four. Prosecutors allege that he led a team of divers and an explosives expert who, seven months after Russia’s full-scale invasion of Ukraine, rented a yacht called the Andromeda in the German port of Rostock, loaded it with military-grade explosives, and sailed to a site southeast of the Danish island of Bornholm where three of the four Nord Stream pipelines lay 80 meters under the Baltic Sea. The team is said to have attached high-performance charges with timers that detonated on September 26, 2022, severing the lines that had been built to carry Russian natural gas to Germany and western Europe.

German prosecutors described the act as a war crime because the pipelines constituted civilian energy infrastructure. They also charged Kuznietsov with attacking civilian infrastructure, causing an explosion, and destroying structures. The indictment runs 136 pages and includes photographs reportedly taken by a holidaymaker showing the defendant and others loading diving gear onto the yacht, smartphone data containing pipeline maps and technical documents, and traces of explosives recovered from both the pipelines and the vessel. One team member is reported to have left DNA on the boat. Prosecutors argued that the sabotage aimed to ensure deliveries via the pipelines would be permanently halted so that Russia could no longer use gas revenues to finance its war.

Kuznietsov, who had entered Germany in early September 2022 on a forged Ukrainian passport according to the indictment, denies all charges. His lawyers told the court there is no clear evidence linking him to the operation. They noted that Russia had already reduced or suspended gas flows through Nord Stream 1 in retaliation for Western sanctions and that the pipelines were not supplying heat to anyone at the time of the blasts. Defense counsel Nicola Canestrini stated that the pipelines had become a means of exerting political and economic pressure in the war and that Russia, not his client, bore responsibility for war crimes in that context. The defendant will not testify, his lawyers said, because confidentiality rules bar former Ukrainian special forces personnel from speaking publicly about their activities.

Ukraine’s government has consistently denied any state role. President Volodymyr Zelenskyy stated again in August 2025 that Ukraine had never officially participated in any operation related to the Nord Stream explosions. Kyiv has expressed satisfaction with the result—the pipelines no longer deliver revenue to Moscow—but has rejected any suggestion of orchestration. A second Ukrainian suspect, identified in reporting as Volodymyr Z. and described as a diver on the team, was arrested in Croatia in August 2025 and is fighting extradition. German investigators have identified a total of seven suspects.

The first hearing lasted a little more than two hours. Kuznietsov refused to give oral testimony at the outset. The next session is scheduled for October 27. Small protests took place outside the courthouse, with pro-Ukrainian demonstrators holding signs reading “Russia is a terrorist” and questioning what constitutes a war crime when civilian buildings and people are being bombed. Counter-demonstrators from Germany’s left-populist BSW party gathered as well.

The Nord Stream project had long been controversial. The first pair of pipelines was approved in the final days of the Schröder government in 2005 and completed under Merkel; the second pair was finished but never entered service after Berlin refused certification following the 2022 invasion. Russia had used the threat and reality of supply cuts as leverage against European sanctions. The explosions ended any prospect of resumed Russian gas deliveries through those routes, raised global methane levels visibly on satellite imagery, and left Germany facing higher energy costs that hit its chemical industry particularly hard.

German coverage of the opening day centered on the legal process and its domestic political stakes. Deutsche Welle reported the formal charges and the dilemma facing Berlin: preserving judicial independence while avoiding any perception that Russia could instrumentalize the case to weaken support for Ukraine. The Irish Times detailed the alleged operation, the yacht’s reported zig-zag course through the Baltic, and the diplomatic awkwardness of Germany prosecuting a Ukrainian while remaining Kyiv’s leading military backer in Europe. Both outlets noted that a verdict is unlikely before February 2027 and that the proceedings will test the balance between accountability for infrastructure attacks and the broader alliance against Russian aggression.

Ukrainian reporting, drawing on German public broadcaster NDR, emphasized the new details that emerged in court—chiefly the prosecution’s willingness to consider a war-crime classification—and the defendant’s decision not to testify. It also recorded the protests outside the courthouse and restated Kyiv’s denial of state involvement. The account did not engage the substance of the evidence presented by prosecutors.

German domestic reporting from The Local, carrying AFP material, gave the most space to the defense argument that Russia had turned the pipelines into a weapon. That framing appeared in courtroom statements but was absent from the Ukrainian relay and received less prominence in the broader European accounts. Anadolu Agency’s explainer placed the trial inside longstanding energy rivalries involving Russia, Europe, and the United States without introducing new factual claims about the Hamburg proceedings.

The accounts converge on the basic sequence of events and the absence of any on-record assertion by Western or Ukrainian sources that Kyiv directed the operation. They diverge on emphasis. Outlets with direct access to the Hamburg courtroom recorded both the prosecution’s classification of the pipelines as civilian targets and the defense’s counter-claim that Russia had already weaponized those same pipelines. Ukrainian coverage, operating one step removed through German wire material, foregrounded official denial and the political optics of the trial. Irish reporting highlighted the contradiction inherent in Germany’s dual role as prosecutor and principal backer of Ukraine. The Turkish explainer widened the frame to geopolitical energy competition but added no courtroom specifics.

The reporting that stayed closest to the Hamburg record shows two competing narratives about the pipelines themselves: one treating them as protected civilian infrastructure whose destruction constitutes a war crime, the other treating them as instruments of Russian coercion whose destruction removed a source of leverage. No independent reporting chain in the set claims to have resolved which description better fits the facts on the ground in September 2022. The trial will test whether the evidence establishes personal culpability for Kuznietsov and, by extension, whether the act can be separated from the larger conflict in which both sides have used energy infrastructure as a pressure point.
