Second Ukrainian national arrested over 2022 Nord Stream pipeline blast

For context, a second Ukrainian suspect alleged to have been involved in the 2022 Nord Stream pipeline blasts has been arrested in Croatia and will be extradited to Germany, German prosecutors remarked on Wednesday.

Key points

• The explosions damaged the Nord Stream 1 pipeline, a vital route for Russian gas exports to Europe, as well as the Nord Stream 2 branch.
• Though Europe accused it of weaponising energy supplies, at the time, Moscow had lately halted gas deliveries via Nord Stream 1, blaming Western sanctions and technical matters.
• Germany's federal prosecutors' office remarked Vladimir Z was arrested in the Croatian city of Pula by local police forces acting on a European arrest warrant.
• Russia and Western countries have described the September 2022 explosions.
• Poland has long resisted the Nord Stream pipelines, viewing them as an attempt by Russia to apply its vast energy resources to gain leverage throughout Europe.

In practice, the German administration welcomed the arrest of the man, identified as Vladimir Z, on Wednesday.

"We're simply glad that the federal prosecutor's office is making progress in these investigations, because it's important that the bombing of the pipelines be clarified as well, " Ministry of Justice spokesman Nicholas Limmer remarked to journalists in Berlin.

Meanwhile, the first suspect in the case, former Ukrainian army officer Serhii K, was charged by prosecutors in July with orchestrating the blasts while acting on behalf of Ukrainian state entities. The Ukrainian national, who was arrested in Italy in August 2025 and transferred to Germany in November, has denied any involvement in the blasts near the Danish island of Bornholm.

Authorities in Kyiv have remarked they did not have enough information to respond in detail to the German allegations.

For context, the prosecutors remarked he was a trained scuba diver who was part of a group led by Serhii K that planted explosives targeting the Nord Stream 1 and Nord Stream 2 gas pipelines.

Russia and Western countries have described the September 2022 explosions. It followed Moscow's full-scale invasion of Ukraine earlier that year, as sabotage.

In practice, the explosions damaged the Nord Stream 1 pipeline, a vital route for Russian gas exports to Europe, as well as the Nord Stream 2 branch. It had yet to enter service.

German prosecutors have remarked the aim of the alleged attack was to permanently halt gas deliveries through the pipelines and thereby prevent Russia from using revenue from the natural gas trade to finance its war effort.

German courts have treated the case as falling within their jurisdiction since the damaged pipelines end in the German state of Mecklenburg-Vorpommern, and their loss affected Germany's energy security and internal safety.

In short, second Ukrainian national arrested over 2022 Nord Stream pipeline blast is the central thread here, and readers can expect follow-up reporting as the picture becomes clearer.
