Ukrainian man arrested in Italy over Nord Stream pipeline blasts

A Ukrainian man suspected to be one of the coordinators of undersea explosions that damaged the Nord Stream gas pipelines between Russia and Germany in 2022 was arrested in Italy on Thursday, authorities said.

The 49-year-old was detained in the early hours in San Clemente, a village inland from Italy's Adriatic coast and 11 kilometers (7 miles) from the resort of Rimini, after Italian authorities were alerted to his possible presence in the country, police in Italy said.

Officers raided a bungalow where the suspect was staying with his family for a few days. Police said he surrendered without resistance.

The man was detained on a European arrest warrant that was issued Monday by German authorities. German federal prosecutors identified him only as Serhii K. in line with local privacy rules.

He was taken to jail in Rimini after his arrest. It wasn’t immediately clear how soon he might be handed over to German authorities.

Undersea explosions on Sept. 26, 2022, damaged pipelines that were built to carry Russian natural gas to Germany under the Baltic Sea.

The damage added to tensions over the war in Ukraine as European countries moved to wean themselves off Russian energy sources, following the Kremlin’s full-scale invasion of Ukraine.

Prosecutors have given little detail so far on their investigation, but said two years ago they found traces of undersea explosives in samples taken from a yacht that was searched as part of the probe.

In a statement Thursday, German prosecutors said Serhii K. was one of a group of people who placed explosives on the pipelines and is believed to have been one of the coordinators.

They said he is suspected of causing explosions, anti-constitutional sabotage and the destruction of structures.

The suspect and others used a yacht that set off from the German port of Rostock, which had been hired from a German company using forged IDs and with the help of intermediaries, prosecutors said.

They didn't give any information on the other people aboard the yacht or say anything about who else might have been involved in coordinating the suspected sabotage, or about a possible motive.

At a briefing in Berlin, German Justice Minister Stefanie Hubig praised what she called an "impressive investigative success."

The explosions ruptured the Nord Stream 1 pipeline, which was Russia’s main natural gas supply route to Germany until Moscow cut off supplies at the end of August 2022.

They also damaged the Nord Stream 2 pipeline, which never entered service because Germany suspended its certification process shortly before Russia invaded Ukraine in February of that year.

Russia has accused the U.S. of staging the explosions, a charge Washington has denied.

The pipelines were long a target of criticism by the U.S. and some of its allies, who warned that they posed a risk to Europe’s energy security by increasing dependence on Russian gas.

In 2023, German media reported that a pro-Ukraine group was involved in the sabotage.

Ukraine rejected suggestions it might have ordered the attack and German officials voiced caution over the accusation.

Swedish and Danish authorities closed their investigations in February 2024, leaving the German prosecutors’ case as the sole probe.
