The Swedish prosecutor's office, which is investigating the undermining of Russian gas pipelines in the Baltic Sea last year, believes that it will be difficult to establish who exactly committed the sabotage.
The relevant statement of the Swedish prosecutor Mats Ljungqvist is cited by the Reuters agency.
The explosions on pipelines connecting Russia and Germany took place on September 26 last year in the economic zones of Sweden and Denmark. The explosion in the Swedish zone occurred at a depth of 80 meters, and the Swedish prosecutor noted that the investigation is difficult.
"We hope to be able to confirm who committed this crime. However, it should be noted that this will most likely be difficult to do given the circumstances," Ljungqvist said in a statement.
"We work unconditionally, turning over every stone and leaving nothing to chance," he assured.
There are now a number of theories about who blew up the pipelines and how, but the official investigation has so far made no conclusive progress.
"There is a lot of information and reports about the sabotage of gas pipes. It is clear that this incident has become an open arena for various attempts to influence. These speculations do not affect the course of the investigation, which is based on facts and information obtained as a result of analysis, examination of the crime scene and cooperation with the authorities of Sweden and other countries," said Ljungqvist.
We will remind, in March materials appeared in the Western mass media suggesting that non-governmental groups, which could include Russians and Ukrainians, could be behind the explosion of the Nord Stream gas pipelines in the Baltic Sea.
The President of Ukraine, Volodymyr Zelenskyi, said that Ukraine was not involved in the explosions, and offered to analyze which players might need such an information leak.
