COPENHAGEN, Denmark (news agencies) — Swedish officials said Wednesday that they have decided to close their investigation into the September 2022 explosions on the underwater Nord Stream gas pipelines which were built to carry Russian natural gas to Germany, saying they don’t have jurisdiction.
Sweden’s investigation was only one of three into the explosions. Denmark and Germany are also examining the blasts.
The attack, which happened as Europe attempted to wean itself off Russian energy sources following the Kremlin’s full-scale invasion of Ukraine, contributed to tensions that followed the start of the war. The source of the sabotage has been a major international mystery.
Public prosecutor Mats Ljungqvist from the Swedish Prosecution Authority said in a statement that its investigation “has been systematic and thorough.”
“Against the background of the situation we now have, we can state that Swedish jurisdiction does not apply.”
The prosecution authority said the primary purpose of its investigation was “to establish whether Swedish citizens were involved in the act and whether Swedish territory was used to carry out the act, and thereby risked damaging Swedish interests or Sweden’s security.” Since Sweden and Swedish interests were not targeted, “Swedish jurisdiction is thus lacking,” it said.
The undersea explosions ruptured the Nord Stream 1 pipeline, which was Russia’s main natural gas supply route to Germany until Russia cut off supplies at the end of August that year.
The blasts also damaged the Nord Stream 2 pipeline, which never entered service because Germany suspended its certification process shortly before Russia invaded Ukraine in February 2022.
Kenneth Øhlenschlæger Buhl of the Royal Danish Defense College said the surprising decision by Sweden to close its probe into the explosions, even though they partly took place in the Swedish economic zone, ”indicates there could have been some kind of a political involvement.”
“There might be a good reason for not going out with a conclusion,” Øhlenschlæger Buhl said. “Sweden stands in a sensitive position as it wants to join NATO and may not want to rock the boat further.”
“Also, one may not want to make public conclusions so that the enemy knows where and how one has obtained this information,” Øhlenschlæger Buhl said.
The detonations took place about 80 meters (260 feet) underwater on the ocean floor in the Baltic Sea in the economic zones of Sweden and Denmark and seismic measurements indicated that explosions took place shortly before the leaks were discovered.
Ljungqvist 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.”
“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.
“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,” he said.
In an emailed response to questions about the impact of the Swedish decision and the state of their own investigation, German federal prosecutors said only that “our investigations are continuing.” They said they are not giving further information at present.
Copenhagen police, which are leading the Danish investigation, said their probe “is still not finally finished, but we expect to be able to make an announcement within a short time.”
Beyond their geopolitical impact, the Nord Stream pipeline leaks were a huge environmental disaster with local wildlife affected and huge volumes of methane discharged into the Baltic Sea in what analysts believe could be the single largest release of methane due to human activity.
More than 16 months after the sabotage there is no accepted explanation. A series of unconfirmed reports variously accusing Russia, the United States and Ukraine are filling an information vacuum as investigations into the blasts continue.
The pipelines were long a target of criticism by the United States and some of its allies, who warned that they posed a risk to Europe’s energy security by increasing dependence on Russian gas.
