Gas is seeping into the Baltic Sea from three separate leaks and an explosion on the Nord Stream 1 and 2 pipelines in what Ukraine calls a "terrorist attack".
The Danish energy agency confirmed there are two leaks on the Nord Stream 1 pipeline and a third in the Nord Stream 2 pipeline in Swedish waters.
Danish armed forces say the surface area of the largest gas leak shows disturbance of a well over one kilometre in diameter.
