By Isabelle Yr Carlsson COPENHAGEN (Reuters) -Two undersea telecommunications cables that were damaged in the Baltic Sea on Dec. 25 appeared to have been torn apart by a strong external force, Finland's Elisa said on Monday,

Finland's Elisa said on Monday that it had finished the repair of its two undersea telecommunications cables that were damaged in the Baltic Sea on Dec. 25. Finland on Dec. 26 seized the Eagle S tanker carrying Russian oil on suspicion that it damaged the Finnish-Estonian Estlink 2 power line and four telecoms cables on Christmas Day by dragging its anchor across the seabed.

Finnish authorities have found and retrieved the anchor of the Eagle S tanker, suspected of damaging cables in the Baltic Sea. Investigators will begin inspecting it on Tuesday. Finnish radio Yle reported that the tanker Eagle S's anchor was located at the bottom of the Gulf of Finland and brought to the surface.

Finnish police said on Sunday they had found tracks that drag on for dozens of kilometres along the bottom of the Baltic Sea where a tanker carrying Russian oil is suspected of breaking a power line and four telecoms cables with its anchor.
