An investigation reveals the alleged involvement of a Ukrainian commander in the sabotage of the Nord Stream gas pipelines.

Russia has summoned the ambassadors of Germany, Denmark and Sweden to express its dissatisfaction with the investigation into the Nord Stream pipeline explosion. Despite eight months of investigations, the responsibility for this underwater attack remains a mystery.

The sabotage of the Nord Stream gas pipelines remains mysterious, according to the Swedish prosecutor who is leading the investigation, with the assumption that a state is responsible. The attack remains linked to Russia's invasion of Ukraine, although those responsible are not yet known despite ongoing investigations in several countries in the region.

Denmark carried out an operation to recover a suspicious object. This object, a smoke buoy, would be linked to the sabotage of the Nord Stream gas pipelines, which took place last September.

The shareholders of the Nord Stream 1 pipeline operator are considering the issue of repairing the damaged pipeline. Following an alleged sabotage, the value of E.ON's stake fell to zero. The operating company is looking for ways to seal and drain the pipeline to limit corrosion caused by seawater.

The sabotage of two gas pipelines in the Baltic rekindles geopolitical tensions between Russia and Europe, in the context of the invasion of Ukraine. While the American and Russian media are putting forward conflicting versions, the investigation into the operation is facing difficulties of attribution.
