A former Ukrainian officer faces trial in Hamburg for the 2022 Nord Stream pipeline explosions. Prosecutors allege state involvement, which Kyiv denies, amid rising political debate in Germany.

On October 14, 2026, the trial of a Ukrainian national accused of sabotaging the Nord Stream gas pipelines began at the Hanseatic Higher Regional Court in Hamburg, Germany. The defendant, identified in court documents as Serhii K. but publicly named as Serhiy Kuznetsov, is charged with being an accomplice to war crimes, causing an explosion, damaging property and disrupting public service.
According to the German Federal Prosecutor's Office, Kuznetsov played a key role in the September 26, 2022, explosions that damaged three of the four pipelines in the Nord Stream 1 and Nord Stream 2 systems. Prosecutors allege that Kuznetsov and a group of others rented a yacht from the German port of Rostock using forged IDs and planted explosive devices on the seabed near the Danish island of Bornholm.
The indictment states that the group detonated at least four bombs weighing between 14 and 27 kilograms (around 31 to 62 pounds) at a depth of 70 to 80 meters. The prosecution asserts that the aim was to permanently disrupt gas deliveries and prevent Russia from using revenues to finance its military operations. Crucially, prosecutors have stated that the suspects were operating "on behalf of state authorities in Ukraine."
Kuznetsov, a former Ukrainian army officer, has pleaded not guilty. His German lawyer, Jes Meyer-Lohkamp, stated that prosecutors "have not provided any direct, conclusive evidence of our client's involvement." The defense has also suggested that the pipelines could be considered legitimate military targets in Ukraine's fight against Russia's invasion.
Ukrainian President Volodymyr Zelenskyy has consistently denied Kyiv's involvement. "Ukraine has never officially taken part in any operation related to the blowing up of Nord Stream," Zelenskyy told reporters in August. A senior Ukrainian official told AFP that Kyiv has "no expectations from the trial."
Reports from German media outlets ARD, Sueddeutsche Zeitung and Die Zeit claim that while in custody in Italy, Kuznetsov told his wife the attack was an "official military operation." His Italian lawyer, Nicola Canestrini, dismissed this as lacking a "smoking gun."
The trial has intensified political debate in Germany regarding support for Ukraine. The right-wing Alternative for Germany (AfD) and the left-wing populist Alliance for Social Justice and Economic Reason (BSW) have criticized German aid to Kyiv. Alice Weidel, co-leader of the AfD, has asserted that the German government must seek financial repayment from Ukraine if involvement is proven, though she has not provided proof of state involvement.
Sahra Wagenknecht, former leader of the BSW, said in 2025: "It is totally absurd that Germany spends many billions on aid for Ukraine but never demands an explanation from [President Volodymyr] Zelenskyy."
Conversely, Roderich Kiesewetter, a lawmaker with the ruling Christian Democrats (CDU), argued that support for Ukraine should continue regardless of the trial's outcome, stating it is in the interest of "our own national security." The German government has refrained from commenting on the trial, citing judicial independence.
The Nord Stream explosions marked the end of a major energy project between Russia and Germany. The trial is the first time evidence regarding the sabotage will be presented publicly under oath. The outcome could significantly influence German public opinion and political dynamics, particularly as the AfD leads in national polls and challenges the government's foreign policy. The proceedings are scheduled to continue through at least February 2027.
