Sweden is investigating a possible breach of an undersea cable off the country's southwestern coast in the Baltic Sea, the coastguard said on Friday, in an area where multiple seabed cables have been damaged in recent months.

Sweden's coast guard has dispatched a vessel to waters east of Gotland. A number of telecommunications and power cables have been damaged in the Baltic Sea in recent months.

COPENHAGEN (Reuters) - Swedish authorities are investigating reports of a breach of an undersea cable in the Baltic Sea, Prime Minister Ulf Kristersson said on social media platform X on Friday.

At a time when the eight NATO nations bordering the Baltic Sea are on high alert after a string of undersea power and internet cables were suspiciously severed, Russia's shadow fleet is getting extra attention.

A ship dragging its anchor was the likely cause of damage to a Russian submarine telecommunications cable in the Baltic Sea, the country’s top telecoms operator said.
