"The conclusion of the investigation is that Swedish jurisdiction does not apply and that the investigation therefore should be closed," the authority said in a statement, adding that "the authorities have a clear view of the incident and that nothing has emerged to indicate that Sweden or Swedish citizens were involved in the attack."
The prosecution authority said the fact that the sabotage at the pipelines was not directed against the interests of Sweden was among reasons to terminate the investigation.
Sweden has handed the materials on the explosions at the Nord Stream pipelines to Germany for its investigation into the matter.
"We have had in-depth cooperation with the investigation conducted by the German authorities. Within the framework of this legal cooperation, we have been able to hand over material that can be used as evidence in the German investigation," Swedish public prosecutor Mats Ljungqvist said.
Germany continues to investigate the Nord Stream pipelines explosions, and Sweden can no longer comment on the cooperation in the case, the official said.
"The German investigation continues and due to the secrecy that prevails in international legal cooperation, I cannot comment further on the cooperation that has taken place. With reference to this, I will also not be able to comment anything further on the conclusions of the Swedish investigation or comment on any suspected persons in the Swedish investigation," Ljungqvist said.
Commenting on Sweden's refusal to investigate the Nord Stream pipelines explosions, Kremlin spokesman Dmitry Peskov said it is noteworthy.
"Germany is a country that has lost a very important asset, there were German firms that took part in a joint venture that was the operator of those pipes that were blown up as a result of this terrorist sabotage against critical infrastructure. A lot of data has been published about who might be behind this, so of course the decision is noteworthy. And it is noteworthy that in this way it [the investigation] was terminated," Peskov told reporters.
Russia will monitor how Germany will react to the investigation, the spokesman added.
Meanwhile Denmark's investigation into the explosions at the Nord Stream pipelines has not been formally completed, a police representative told Sputnik.
"In regards to the Danish investigation it is not formally concluded yet, but we expect to be able to issue a statement sometime in the near future," the representative said.
No official results of the investigations have yet been announced, but Pulitzer Prize-winning US investigative journalist Seymour Hersh published a report in February 2023, saying the explosions were organized by the US government with the assistance of authorities in Norway. Washington has denied any involvement in the attack.
