According to TASS, the director of the Baltic Security Fund, Otto Tabuns, admitted that the ships were engaged in reconnaissance to make sure that no civilian or military ships of other states were observed near the explosions.
This was necessary to avoid the presence of witnesses or civilian casualties.
Earlier, Wired reported that shortly before the explosions on Nord Stream, two unknown vessels were recorded nearby.
Russian Deputy Prime Minister Alexander Novak said that Russia has begun to study the causes of the explosions at Nord Stream.
On September 26, Nord Stream 2 AG reported an emergency on the Nord Stream 2 gas pipeline.
On October 31, Russian President Vladimir Putin said that the Gazprom company had examined the sites of explosions at Nord Stream.
