Ukrainian Officer on Trial for Nord Stream Pipeline Blasts
Confirmed
In Short: A Ukrainian former military officer is on trial in Germany for allegedly organizing the secret operation that blew up the Nord Stream gas pipelines in 2022.

A Ukrainian former military officer is standing trial in Germany, accused of organizing the secret operation that blew up the Nord Stream gas pipelines in 2022, according to Al Jazeera (Qatar) and Arabnews (Saudi Arabia).
On September 26, 2022, Swedish seismologists detected several blasts, some 17 hours apart, as reported by Al Jazeera (Qatar), Arabnews (Saudi Arabia), Marinetechnologynews, Newscord, Oedigital, and Themoscowtimes.
The trial, which opened at Hamburg's Higher Regional Court on October 14, 2026, is expected to run into February 2027, according to The Times of Israel (Israel).
Serhii K., as identified by German prosecutors, faces charges of causing an explosion, damaging property, disrupting public service, and being an accomplice to war crimes by attacking civilian infrastructure, as reported by BBC (United Kingdom) and The Times of Israel (Israel).
Serhii K. has denied any involvement in the blasts that ruptured the 1,200-km (750-mile)-long Baltic Sea pipeline, as reported by Arabnews (Saudi Arabia), Marinetechnologynews, Oedigital, and Themoscowtimes.
The Nord Stream system, lying at a depth of 80 to 110 metres under the Baltic and built by Russian gas concern Gazprom to supply up to 110 billion cubic metres of gas to Germany, was formerly at the core of economic ties between the two countries, according to Marinetechnologynews, Oedigital, and Themoscowtimes.
Germany previously received half its natural gas imports through the Nord Stream 1 pipeline, which allowed Russia to bypass Soviet-era pipelines transiting Ukraine, as reported by Oedigital and Themoscowtimes.
The explosion of Nord Stream sealed the end of Germany's longstanding dependence on Russian natural gas, although Moscow had already cut supplies over Berlin's support for European sanctions following Russia's February 2022 invasion of Ukraine, as reported by Oedigital and Themoscowtimes.
Croatian authorities have arrested another man, identified as Vladimir Z., who prosecutors believe was one of the divers in the team, according to Marinetechnologynews, Oedigital, and Themoscowtimes.
Stefan Meister, of the German Council on Foreign Relations, told RFE/RL that the crucial question was “How much came from the top of the Ukrainian political system or how much was prepared by some insiders in the intelligence service?” as reported by Newscord.
A senior Ukrainian official told AFP that Kyiv has “no expectations from the trial,” as reported by The Times of Israel (Israel).
Russia said on Monday it expected a “just verdict” naming the perpetrators and those who ordered the operation, as reported by Al Jazeera (Qatar), Arabnews (Saudi Arabia), Marinetechnologynews, Newscord, Oedigital, and Themoscowtimes.
