Germany’s federal prosecutor’s office filed an indictment against a Ukrainian national over the explosions of the Nord Stream gas pipelines.

According to an indictment filed on June 30, prosecutors accuse a man of acting as a co-perpetrator in a war crime involving an attack on civilian objects, causing an explosion, destroying buildings and disrupting public services.

Prosecutors said on Thursday the aim of the operation was to permanently disrupt gas supplies through the pipelines and prevent Russia from using the revenue from natural gas trade to finance its war effort.

German courts have treated the case as falling within German jurisdiction because ​the pipelines run from Russia through the Baltic Sea to Lubmin, Germany.

The suspect was arrested by Italian police in the province of Rimini on August 21, 2025, in execution of a European arrest warrant and extradited to Germany in November 2025.

He and the other members of the group allegedly boarded a sailing yacht suitable for the open sea, which had been previously chartered from a German company in Rostock by intermediates using fake IDs, prosecutors said in a statement.

According to the prosecutors’ release, the accused and his accomplices comprising of several professional divers, a skipper and an explosives expert, allegedly transported large quantities of high-performance, military-grade explosives through international waters to a location near the Danish island of Bornholm, where the pipelines run along the seabed.

As they said, the group led by the accused placed various explosive devices fitted with time fuses on the pipelines.

They said the plan was to “destroy the “Nord Stream 1” and “Nord Stream 2” gas pipelines” in 2022 and described the accused as “military personnel.”

“The explosive devices detonated on 26 September 2022, causing severe damage to both pipelines. Prior to the incident, ‘Nord Stream 1’ had been used to transport approximately half of Germany’s annual natural gas demand for energy production,” they said.

Kyiv has denied involvement in the case, media reports say.
