A Ukrainian national suspected of involvement in the 2022 sabotage of the Nord Stream pipelines has been arrested in Croatia, European prosecutors confirmed on August 19, 2026, adding fresh momentum to a sprawling cross-border investigation that has already drawn in Poland, Italy, and Germany [1].
Prosecutors identified the suspect only as "Vladimir Z," a trained scuba diver, but he is widely understood to be Volodymyr Zhuravlyov — a man whose legal journey through Europe has already produced one dramatic courtroom moment [1].
A Suspect Who Has Been Here Before
Zhuravlyov is not new to the dock. He was arrested in Poland in 2025 on a German extradition request related to the same undersea plot, but a Polish judge refused to hand him over [1]. The judge's reasoning was striking: if Ukraine was responsible for the attack, the act was, in the court's view, a "just" one. Zhuravlyov was released, prompting what reporters described as a ripple of surprise from the crowd in court and a smile from the man himself [1].
His re-arrest in Croatia now gives German authorities a second opportunity to secure his extradition. Officials said that once brought to Germany, he will face an investigating judge on charges of causing explosions and sabotage [1].
The Wider Case: A Second Defendant Already in Germany
Zhuravlyov is not the only Ukrainian national caught up in the investigation. The other named suspect is Serhiy Kuznetsov, a former Ukrainian military officer [1]. Kuznetsov was arrested in Italy in August 2025 and subsequently extradited to Germany, where he is set to stand trial [1]. He has denied any responsibility for the explosions and appeared before a court in Hamburg in June [1].
Prosecutors allege that Kuznetsov led a team that rented a yacht at Rostock, on Germany's Baltic coast, and used it to plant explosives on the pipelines near the Danish Baltic Sea island of Bornholm [1]. The alleged operational role attributed to Kuznetsov — commanding the team on the water — places him at the center of the prosecution's theory of the attack.
What the Evidence Shows
German investigators, in a letter sent to the United Nations Security Council following the blasts and reported by Reuters at the time, stated that "traces of subsea explosives were found in the samples taken from the boat" linked to the suspects [1]. That forensic detail has been central to building the case against both men.
The explosions in September 2022 ruptured Nord Stream 1, which was in operation at the time, and Nord Stream 2, which had been completed but had not yet entered service [1]. The blasts effectively ended any near-term prospect of Russian gas flowing to Germany through those routes, dealing a significant blow to an already strained energy relationship between Moscow and Berlin.
Blame, Denial, and a Shifting Narrative
In the immediate aftermath of the explosions, suspicion fell heavily on Russia, given the pipelines' role in a broader geopolitical standoff over the war in Ukraine. Over time, however, evidence pointing toward Ukrainian involvement began to surface, shifting the focus of Western investigations [1].
Officials in Kyiv have repeatedly denied any role in the sabotage [1]. Ukraine has not been formally charged in any jurisdiction, and no Ukrainian state actor has been named as a defendant in the German proceedings. The cases against Zhuravlyov and Kuznetsov concern their alleged individual conduct, not official Ukrainian policy — a distinction that will likely feature prominently in any future trial.
The Polish court's earlier reasoning — that even if Ukraine were responsible, the act could be considered justified given the context of Russia's full-scale invasion — illustrates the deeply political terrain that prosecutors and judges must navigate. Whether Croatian courts will take a similar view, or whether the extradition will proceed smoothly to Germany, remains to be seen.
What to Watch Next
Several threads will determine how this story develops in the coming months. The most immediate question is whether Croatia's judiciary will approve Zhuravlyov's extradition to Germany, or whether his legal team will mount a challenge along the lines of the successful Polish defense. The outcome of Kuznetsov's trial in Hamburg will also be closely watched: it is the first time any suspect in the Nord Stream case will face a full judicial reckoning, and the evidence presented there could shape how the broader investigation is understood. Finally, investigators and observers will be looking for any indication of whether the alleged operation was sanctioned at a higher level — a question that neither prosecution has publicly answered.
