The prosecutor leading Sweden’s investigation into the 2022 Nord Stream gas pipeline explosions in the Baltic Sea will make an announcement on the case on Wednesday, his office said on Tuesday.

Sweden’s public prosecutor’s office said on Monday it plans to announce a decision sometime this week on whether to drop the case, press charges or ask for someone to be taken into custody.

The multibillion-dollar Nord Stream pipelines that transport Russian gas to Germany under the Baltic Sea were damaged after a series of explosions in Swedish and Danish waters, releasing huge amounts of methane into the atmosphere.

Danish police said the pipelines were hit by powerful explosions, and Swedish investigators confirmed traces of explosives found at the scene conclusively indicated sabotage had taken place.
