Swedish Prime Minister Magdalena Andersson said on Monday that Sweden will not share the results of an investigation into the Nord Stream gas pipeline explosions with Russian authorities or Gazprom, Reuters reported.

A Swedish investigation into the explosions on the Nord Stream 1 and 2 gas pipelines from Russia to Europe has found evidence of detonations, and prosecutors suspect sabotage.

Last week, Russian Prime Minister Mykhailo Mishustin sent a letter to the Swedish government demanding that the Russian government and Gazprom be involved in the investigation, which Sweden refused.

On Monday, Andersson said that Sweden will not even share with Russian authorities the results of the investigation into the explosions that happened in Sweden’s economic zone.

“In Sweden, our preliminary investigations are confidential, and that of course also applies to this case,” she told reporters.

However, Andersson said that Sweden does not have the authority to ban Russian ships from visiting the blast sites now that the investigation at the scene has been completed.

“The Swedish economic zone is not an area that Sweden owns. Now we have removed the borders and other ships can stay in the zone, that’s the rules,” she said.
