Swedish prosecutors said on Friday that explosions at the Nord Stream gas pipelines in September were the result of “gross sabotage”. Their ongoing investigation also found “traces of explosives on several of the foreign objects found” at the scene of the blast. The findings confirm the suspicions of many European policymakers that the explosions, which hit the major underwater natural gas pipelines in the Baltic Sea that connect Russia to Germany, were deliberate. Prosecutors gave no further details, but said the “complex” investigation was ongoing.
