Finland says a ship affiliated with Russia's "shadow fleet" is linked to a 60-mile-long anchor drag mark on the seafloor. A power cable in the Baltic Sea was severed last week.

Finnish authorities said on Saturday they are moving an impounded tanker closer to port after boarding the vessel carrying Russian oil earlier this week on suspicion it had damaged an undersea power line and four telecoms cables.

Finnish police intend to transport the Eagle S, a Russia-linked tanker the authorities seized after suspecting it of intentionally damaging a Baltic Sea power cable, to shore. The tanker is to be moved from the Gulf of Finland to an anchorage near the Finnish port of Kilpilahti to facilitate the investigation,
