Sweden's public prosecutor has concluded a 16-month investigation into the underwater explosions that destroyed two pipelines transporting Russian gas to Germany. The inquiry, which aimed to determine any Swedish involvement or use of Swedish territory, found no basis for Swedish jurisdiction. The Swedish intelligence service, Sapo, shared its findings with other nations, while German and Danish authorities continue their investigations into the September 2022 blasts. The closure of the Swedish inquiry may aid the German investigation if Sapo uncovered additional information. The pipelines, constructed by Russia's Gazprom, were targeted in the Baltic Sea. Although Nord Stream 2 remained unused due to Germany's suspension after Russia's invasion of Ukraine, Russian vessels were linked to suspicious activities before the explosions. Russia denounced the sabotage as international terrorism, blaming the US and UK. Recent scrutiny has focused on a chartered yacht, the Andromeda, which stopped in Denmark and Poland prior to the blasts. While Ukraine denied involvement, speculation emerged regarding a potential connection to a pro-Ukrainian group. German Defence Minister Boris Pistorius cautioned that the Nord Stream explosions might have been a "false flag" operation to implicate Ukraine.
