German Prosecutors Charge Ukrainian National With Ordering 2022 Nord Stream Pipeline Sabotage

German federal prosecutors have formally charged a former Ukrainian army officer with orchestrating the September 2022 sabotage of the Nord Stream gas pipelines. The indictment, filed at a regional court in Hamburg, accuses the suspect of acting as a co-perpetrator in a war crime by attacking civilian infrastructure and severely disrupting public services.[1][2]

The suspect, identified under German privacy laws as Serhii K. and named in some reports as Serhiy Kuznietsov, was an officer in the Ukrainian military at the time of the blasts. Prosecutors allege that he did not act independently, but rather developed the sabotage plan alongside other military personnel "on the orders of state authorities in Ukraine."[2][3]

According to the indictment, Serhii K. led a specialized team comprising professional divers, a skipper, and an explosives expert. The group allegedly entered Germany in September 2022 using forged Ukrainian passports and chartered a sailing yacht, the Andromeda, using falsified identification documents.[1][5]

Investigators say the team used the Andromeda to transport large quantities of military-grade explosives through international waters. They navigated to a location near the Danish island of Bornholm, where divers attached the charges directly to the Baltic Sea floor pipelines and set time fuses. The resulting blasts ruptured three of the four Nord Stream 1 and 2 conduits.[4][6]

German prosecutors assert that the primary objective of the sabotage was to permanently sever the flow of Russian natural gas to Europe. By crippling the pipelines, the operation aimed to prevent Moscow from utilizing lucrative energy revenues to finance its ongoing full-scale invasion of Ukraine, which had begun months earlier.[1][2]

Serhii K. was initially apprehended in Italy in August 2025 while on vacation. Following a lengthy extradition process, he was transferred to German custody in November 2025 and has remained in pretrial detention in Hamburg. He has consistently denied any involvement in the pipeline bombings.[3][5]

Despite his denials, his Italian defense attorney, Nicola Canestrini, stated that the legal team welcomed the indictment. "We do not fear the indictment — we demand that the facts be established, and in public," Canestrini remarked, signaling a readiness to contest the charges in open court.[1]

German courts have claimed jurisdiction over the international incident because the damaged pipelines terminate in Lubmin, a coastal town in the northeastern state of Mecklenburg-Vorpommern. Authorities argue the destruction directly compromised Germany's internal safety and triggered a severe, nationwide energy security crisis.[1][4]

The Ukrainian government has repeatedly denied official involvement in the Nord Stream sabotage. Following the announcement of the charges, Ukrainian President Volodymyr Zelenskyy stated that Kyiv had not yet received the full details of the indictment and would respond once relevant authorities had reviewed the documents.[2][3]

The formal accusation that a Ukrainian state entity directed an attack on German energy infrastructure threatens to strain the vital alliance between the two nations. Germany currently stands as Ukraine's second-largest supplier of military aid, making the diplomatic fallout of a public war crimes trial highly sensitive for both Berlin and Kyiv.[2][6]
