Investigators have found traces of explosives at the site of the damaged Nord Stream pipelines, confirming sabotage has taken place, a Swedish prosecutor said on Friday.
Swedish and Danish authorities are investigating four holes in the Nord Stream 1 and 2 pipelines that connect Russia and Germany via the Baltic Sea and have become a focal point in the Ukraine crisis.
Denmark said last month that a preliminary investigation had found the leaks were caused by powerful explosions.
“Analysis now carried out shows traces of explosives on several of the recovered objects,” Sweden’s public prosecutor’s office said in a statement.
“The research is very complex and comprehensive. The ongoing investigation will determine whether any suspects can be identified,” it added.
The prosecutor’s office declined to comment further.
