The Christmas Day cutting of four Internet cables and one power cable will cause NATO to boost its presence in the Baltic Sea. Finland last week seized the Eagle S ship, carrying Russian oil, under suspicion of being behind the cuts. “NATO will enhance its military presence in the Baltic Sea,” NATO secretary general Mark Rutte said.

Finnish investigators have linked damage to the Estlink-2 power cable in the Baltic Sea to a Russian-linked vessel, the Eagle S. Anchor drag marks stretching nearly 100 kilometers were discovered, and an investigation is underway to determine intent,

General Mark Rutte says the military alliance will step up patrols in the Baltic Sea area as Finnish investigators work to establish whether a ship linked to Russia sabotaged undersea cables there this week.

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.

Finnish investigators probing the damage to a Baltic Sea power cable and several data cables say they have found an anchor drag mark on the seabed, apparently from a Russia-linked vessel that has already been seized.
