Denmark Rejects Cooperation Request in Nord Stream Sabotage Investigation
Copenhagen, Denmark — Denmark has declined to assist Germany with parts of its investigation into the sabotage of the Nord Stream gas pipelines, according to reports, adding another complication to the multinational probe into the 2022 explosions in the Baltic Sea.

The Nord Stream pipelines, which were designed to carry Russian natural gas to Germany beneath the Baltic Sea, were damaged by a series of underwater explosions in September 2022. The blasts caused major leaks and triggered investigations by authorities in several European countries.
German investigators have been pursuing leads concerning the people allegedly involved in planning and carrying out the sabotage. The investigation has included cooperation with European partners and examination of evidence collected from different countries.
Recent reports indicate that Denmark did not agree to a German request for assistance in a particular aspect of the investigation. Danish authorities have previously conducted their own inquiries into the pipeline explosions but concluded that there were no sufficient grounds to pursue a criminal case in Denmark.
The Danish investigation was closed in February 2024. Danish authorities said at the time that the explosions appeared to have been deliberate but did not identify those responsible.
Sweden also previously ended its own investigation into the explosions, transferring relevant evidence to German authorities.
Germany has continued its investigation and has pursued suspects believed to have played roles in the operation. The case has attracted international attention because of the geopolitical importance of the pipelines and the potential implications of the sabotage.
The identity and nationality of those ultimately responsible remain subjects of dispute and investigation. Various theories have emerged since the explosions, but investigators have stressed the importance of evidence rather than speculation.
The Nord Stream case has become one of Europe’s most closely watched international criminal investigations because it involves underwater infrastructure, alleged sabotage and multiple jurisdictions.
German authorities are continuing to assess evidence and pursue legal avenues available to them. Any individuals eventually charged will have the right to defend themselves in court and are presumed innocent unless convicted.
Denmark’s decision not to provide the requested assistance does not itself establish responsibility for the pipeline explosions. The circumstances surrounding the sabotage remain under investigation.
Authorities in Europe continue to face the challenge of determining exactly who planned the operation, how it was organized and who carried it out.
