Finnish investigators say they found traces along the nearly 100-kilometre-long seabed around the site of an undersea power cable damaged on Christmas Day in an alleged act of Russian sabotage.
The Eagle S vessel, registered in the Cook Islands, was found and seized by Finnish authorities on December 26, off the country's southern coast.
Its anchor was reported to have been lowered and dragged, damaging the Estlink-2 undersea power supply cable.
