(Bloomberg) -- The leaks on the Nord Stream pipelines are forming an area of natural gas bubbles about 1 kilometer (1,090 yards) in diameter in the Baltic Sea, a video released by the Danish army showed.

Another smaller area with gas bubbles measured about 200 meters in diameter, according to the footage, which the Danish Defense shared on its website and via its Twitter account on Tuesday. 

Germany suspects the Nord Stream gas pipeline system was damaged by an act of sabotage, in what would amount to a major escalation in the energy standoff between Russia and Europe.

The footage, which included images of the leaks from both Nord Stream and Nord Stream 2, was conducted by a Danish helicopter deployed in the area. The army has also said it will send a warship to the Danish Baltic Sea island of Bornholm.
