According to the source, the service to track the movement of vessels showed that the Swedish warship entered the area near the pipelines twice, where leaks were soon discovered.
At the same time, the Swedish Navy pointed out that maritime surveillance was performed in these areas, the purposes of which were not mentioned. The report noted that on the night of the explosions, the Swedish ship was not in the area.
In late September, a gas leak was detected at four locations on the Nord Stream 1 and Nord Stream 2 pipelines in the Baltic Sea near the Danish island of Bornholm.
Last weekend, according to Denmark, gas leaks from both pipelines stopped.
Danish, Swedish, and Russian authorities are investigating the incident: the Swedish Security Service is provisionally treating it as sabotage, while the Russian Federal Security Service considers it international terrorism.
On Monday, Gazprom reported that after the breaks, the pressure in the pipelines was stabilized and the leaks had stopped.
The Russian company began pumping gas through the undamaged Nord Stream 2 pipeline to verify its integrity.
Last week, Russian Foreign Ministry Spokeswoman Maria Zakharova said that Russia had called an emergency meeting of the United Nations Security Council to address possible sabotage on the Nord Stream pipeline system.
