Swedish investigator suspects state actor involvement in Nord Stream attacks.

The involvement of a state actor in the Nord Stream pipeline attacks last year is the "absolute main scenario", according to the Swedish prosecutor investigating the incident. The blasts occurred in the economic zones of Sweden and Denmark, and both countries say the explosions were deliberate, but have yet to determine who was responsible. The investigation continues, and while no conclusion has been drawn, the type of explosive used has ruled out a large number of actors. Nord Stream 1 and Nord Stream 2 were built by Russia's state-controlled Gazprom to pump 110 billion cubic metres of natural gas a year to Germany.
