Thursday, a team of investigators analyzing multiple explosions that shook the Nord Stream pipeline network determined that "detonations" caused damage to the pipelines, while suspicions of sabotage persist.
Danish and Swedish authorities have checked four sites along the Nord Stream 1 and Nord Stream 2 pipelines following the discovery of what may have been the largest methane leak in history last week in the Baltic Sea off the coast of Denmark.
"There have been detonations near Nord Stream 1 and 2, within the Swedish economic zone, resulting in extensive damage to the gas pipelines," Swedish security police said in a statement quoted by Reuters.
The area is no longer sealed off and the leaks have ceased, but authorities have stated that the inquiry continues as some materials require further research.
"The continued investigation will show whether anyone can be suspected of, and later prosecuted for, this crime," concluded the statement.
Both Moscow and Western countries have leveled accusations of "sabotage." at each other.
The Royal Navy reported on Monday that nations such as the United Kingdom and the Netherlands have increased their maritime security presence in the North Sea in response to the gas pipeline leaks.
Over the weekend, NATO, of which Sweden is in the process of becoming a member, accused Russia of attacking pipelines with "deliberate, reckless and irresponsible acts of sabotage."
Russia, which has accused the United States of employing underwater "robots" to target the pipelines, has already stated that it will not recognize the results of any probe in which it is not directly involved.
Kremlin spokesperson Dmitry Peskov told reporters on Thursday, via Reuters, that diplomatic channels have advised them that there are currently no intentions to urge the Russian side to participate in investigations.
According to Peskov, the Kremlin does not believe a probe that excludes Russia can be objective.
However, Sweden has already rejected the notion that Moscow should take a role in its investigation, stating that "it wasn’t up for discussion."
During a conference on Tuesday, Swedish Defense Minister Peter Hultqvist was quoted as saying, "We don't usually involve foreign powers in our criminal investigations," "That is the core strategy. It is not open for debate."
