Croatian police arrested a Ukrainian diver in Pula on 19 August 2026 over his alleged role in the 2022 Nord Stream pipeline explosions, Croatian broadcaster HRT reported. German prosecutors confirmed to AP that the suspect was Volodymyr Zhuravlov (Zhuravliov in Ukrainian official transliteration). Legal Tribune Online reported that he was detained on the set of Zmiinyi (Snake) Island.

The arrest gives German prosecutors a third chance to secure Zhuravliov after two attempts in Poland failed. If Croatia extradites him, he would become the second suspected member of the alleged team to face proceedings in Germany. Berlin has pursued other suspects in the Nord Stream case across Europe, but the identity of the person who ordered the sabotage remains unknown.

Previous arrests and arrest attempts

Germany’s Federal Public Prosecutor’s Office said Zhuravliov was a trained scuba diver who took part in the dives needed to place explosives on Nord Stream 1 and 2 near Denmark’s Bornholm island. Prosecutors say the group sailed from Rostock aboard a yacht that middlemen rented from a German company using forged identity documents.

The 2024 European arrest warrant accuses Zhuravliov of jointly causing an explosion, anti-constitutional sabotage, and destroying structures. He would appear before an investigating judge at Germany’s Federal Court of Justice following extradition, prosecutors said. A Croatian court must first approve his surrender.

LTO reported that investigators first sought Zhuravliov’s arrest in Poland in the summer of 2024, but he crossed into Ukraine before police detained him. Polish police arrested him near Warsaw in autumn 2025. However, a court rejected Germany’s extradition request after finding that the pipelines could be treated as a legitimate military target during an armed conflict. Zhuravliov has denied involvement.

His lawyer, Tymoteusz Paprocki, told AP that Zhuravliov understood the Polish ruling applied only within Poland.

Another Ukrainian suspect, Serhii K., was arrested near Rimini in August 2025 and extradited to Germany that November after unsuccessful appeals. Prosecutors allege he coordinated the operation rather than joining the dives. They charged him in Hamburg in June 2026.

What was Nord Stream?

Nord Stream 1 and 2 ran beneath the Baltic Sea, carrying—or designed to carry—Russian gas directly to Germany while bypassing Ukraine. Explosions on 26 September 2022 damaged three of their four lines at a depth of about 80 meters.

No court has established who ordered the attack. Ukraine’s Prosecutor General’s Office says no facts demonstrate Ukrainian state involvement and is examining whether Russia staged a false-flag operation using Ukrainians. LTO reported that Germany’s Federal Court of Justice found strong grounds in December 2025 to believe that a state had initiated and directed the sabotage, but did not identify which state.

A deliberately set fire at a Tallinn building used by Milrem Robotics did not disrupt its deliveries of military ground robots to Ukraine, CEO Kuldar Väärsi told Reuters on 19 August 2026. Estonian prosecutors said three suspects had been detained in Latvia.

The Milrem arson case fits in a broader pattern of suspected or confirmed sabotage against Ukraine’s military supply chain. Similar attacks throughout Europe have hit plants making drones, thermal optics, and other equipment for the front. Milrem supplies unmanned ground vehicles (UGVs) that help Ukrainian units move supplies and evacuate wounded without putting drawing upon valuable manpower.

The fire broke out overnight on 15 August in Tallinn’s Lasnamäe district after a resident reported suspicious activity. Nobody was injured, and Milrem has not disclosed what was damaged.

Milrem says it is one of only two foreign suppliers with unmanned ground vehicle (UGV) fleets in active Ukrainian service and expects more than 200 of its systems to be operating there by year-end.

The Netherlands is funding more than 150 additional Milrem vehicles for Ukraine. In June, Milrem and VDL Defentec opened a Dutch production line to support the delivery of more than 100 THeMIS UGVs. Väärsi the fire had not affected production, supply chains, or delivery schedules for this year or next.

Unmanned ground vehicles (UGVs) are tracked or wheeled machines with no crew aboard. ArmyInform reported that Ukrainian troops use them to carry ammunition, fuel, and food along exposed routes. A Ukrainian commander identified only as Nazar told ArmyInform that frontline units still rely mainly on UGVs for logistics, although some robots carry explosives.

Three suspects detained as investigators examine possible Russian role

State Prosecutor Gardi Anderson said prosecutors suspect all three detainees of taking part in the arson. Latvian authorities are holding them while the two countries arrange their transfer to Estonia. An Estonian court approved prosecutors’ requests to place two in pretrial detention. A decision on the third remained pending.

Estonian Prime Minister Kristen Michal said investigators were examining whether the fire was the result of sabotage and whether Russia was involved. Authorities have not disclosed the suspects’ alleged motive, whether anyone directed them, or released evidence connecting the attack to Moscow.

Arson has hit other European suppliers to Ukraine

In March, a fire destroyed nearly all of the production capacity at a Czech plant that makes drones and thermal optics for Ukraine. Authorities detained four suspects while investigating possible terrorism and Russian involvement.

Lithuania also charged six people over an attempt to burn a factory supplying radio-wave scanners to Ukraine. Investigators said Russia-based organizers with GRU links coordinated the operation and connected the network to attempted attacks elsewhere in Europe.

Russia has denied Western accusations that it conducts sabotage in Europe.
