The bloc announced new steps to prevent threats to undersea lines after Sweden discovered damage to one east of Gotland island.

Swedish police said on Friday they were investigating a suspected case of sabotage of an undersea telecoms cable in the Baltic Sea, and the country’s coast guard deployed a vessel to the area where multiple seabed cables have been damaged in recent months.

Swedish police have launched an investigation after new reports of potential cable sabotage in the Baltic Sea. Authorities in Stockholm are looking at a suspected crime in the Swedish economic zone. They have not released any details but said they have deployed equipment to determine if this is a new break or an unsuccessful repair.
