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 authorities say they are investigating a damaged cable that was discovered in the Baltic Sea, the latest in a string of recent incidents of ruptured undersea cables that have heightened fears of Russian sabotage and spying in the region.
