Nord Stream Sabotage: Everything You Need to Know About the Upcoming Trial

Seven months after Russia’s 2022 invasion of Ukraine, explosions ripped through the Nord Stream gas pipelines—Russia’s controversial energy highway to Europe—deep in the Baltic Sea. Now, as Germany prepares for a high-stakes trial, we break down one of the most mysterious acts of modern sabotage.

What are the Nord Stream pipelines?

Nord Stream 1 and 2 were designed to funnel Russian gas directly to Europe via Germany. Owned primarily by the Russian firm Gazprom, these pipelines were subjects of intense debate long before the war, primarily due to European concerns over reliance on cheap Russian hydrocarbons.

• Nord Stream 1: Announced in 1997, it became operational in 2011.
• Nord Stream 2: Completed in September 2021, but Germany suspended it just days before the 2022 invasion of Ukraine.

In September 2022, underwater explosions near the Danish island of Bornholm released plumes of gas, marking an unprecedented act of destruction against energy infrastructure.

The Investigation and Arrests

While fingers were initially pointed at Russia, the investigative path shifted significantly. Swedish prosecutors were the first to label the event "gross sabotage" after discovering traces of explosives at the site. Although Denmark and Sweden eventually closed their investigations due to jurisdiction issues, Germany continued its pursuit.

In 2024, German authorities issued an international arrest warrant for a Ukrainian national. Since then, two Ukrainian men have been detained:

1. Serhii Kuznietsov (Serhii K): A former Ukrainian soldier arrested in Italy in 2025 and extradited to Germany. He is the primary defendant in the trial starting this Wednesday in Hamburg.
2. Volodymyr Zhuravlov: Detained in Croatia; a local court has approved his extradition to Germany, though his legal team may appeal.

The Trial Ahead

Serhii K faces charges including the "war crime" of attacking civilian objects, destruction of infrastructure, and causing an explosion. Prosecutors allege the group used a sailing yacht rented with forged documents to carry out the attack. The defendant denies all wrongdoing, and the Ukrainian government has officially denied involvement.

Geopolitical Context

The blasts occurred at a time of extreme tension. For critics of the project, like Polish Prime Minister Donald Tusk, the issue was never just about the sabotage, but about the pipelines being built in the first place. The trial is expected to last until February next year, with Germany aiming to uncover the full truth behind this complex international incident.
