An unidentified object has been found in the vicinity where the Nord Stream pipeline was hit by an explosion in September, Danish authorities said on Tuesday

A major gas leak was discovered on the Danish island of Bornholm after explosions at Nord Stream 1 and 2 in September.

Danish authorities have received information from the Russian company Gazprom, which owns the gas pipeline, that a small object has been found on Nord Stream 2.

– The relevant authorities have assessed that the observation does not pose an immediate security risk, and that there is no immediate danger to people or vessel traffic in the area. Authorities are investigating and following the situation closely, the Danish Foreign Ministry wrote in an email to Swedish news agency TT.

Gazprom has received permission from the Danish authorities to survey the damage done to the gas pipeline.

The information comes after Russian President Vladimir Putin said earlier on Tuesday that Gazprom had found an antenna-like object about three miles from where the explosion occurred.

“Experts believe that it could be an antenna capable of receiving signals to detonate explosives,” Putin said, further implying that state actors must have been behind the attack, saying the United States benefited from it.

German and American media have recently reported that pro-Ukrainian groups may be behind it, but Russia, which has always pointed the finger at the West, has dismissed that explanation.
