A preliminary investigation into damage to the two Nord Stream gas pipelines in the Danish Baltic Sea shows that the leaks were caused by “powerful explosions,” the Copenhagen police said in a statement.
Police added that further investigations into the breaks in the Nord Stream 1 and 2 pipelines in Denmark’s exclusive economic zone on September 26 would be conducted jointly by Copenhagen police and the Danish security and intelligence service.
The Danish findings appeared similar to those of Swedish prosecutors, who said two other holes in the pipelines also appeared to have been caused by explosions and that the case was being investigated as an act of gross sabotage.
On Tuesday, the Swedish newspaper Expressen reported that a section of at least 50m (164ft) is missing from the ruptured Nord Stream 1 gas pipeline in the Baltic Sea, after filming what it believes were the first publicly released footage of the damage.
Swedish and Danish authorities have been investigating four leaks in the pipelines that connect Russia and Germany via the Baltic Sea and have become a focal point in the Ukraine crisis.
The Kremlin said on Tuesday that the international investigation was set up with the intention of blaming Russia.
Kremlin spokesman Dmitry Peskov said “elementary logic” showed that the damage to the pipeline was a blow to Russia’s interests.
He said the investigation was conducted “in secret” and without Moscow’s intervention.
Captured with a small remote-controlled submersible vehicle, or submarine drone, Expressen’s video showed bent metal and a wide-open pipeline in murky water at the bottom of the Baltic Sea.
Parts of the pipeline appeared to have straight, sharp edges, while others were distorted, the images showed at a depth of about 80 meters (262 feet).
The video was recorded Monday, Expressen said.
The Danish police cannot say when the investigation is expected to be completed.
“It is too early to say anything about the framework within which international cooperation with, for example, Sweden and Germany will take place, as it depends on several factors,” the Copenhagen police said.
Photos and video footage show bubbles rising to the surface of the seawater after the spill last month.
World leaders have called the damage an act of sabotage and Moscow has tried to blame the West, suggesting the United States could turn a profit.
Washington has denied any involvement.
