Estonian naval ships are taking part in stepped-up patrols in the Baltic Sea by NATO countries after undersea power and communications cables have been damaged in recent months.

Finnish police said on Tuesday they have recovered a lost anchor from the bottom of the ocean as part of an investigation of suspected sabotage against power and internet cables in the Baltic Sea. Fin

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.

The Eagle S, thought to be part of Russia’s “shadow fleet,” was detained in December following suspected sabotage.

On Tuesday, January 7, specialists discovered the anchor of the tanker Eagle S at the bottom of the Gulf of Finland. The vessel likely "lost" it during the breakage of several underwater cables, Yle reports.

Finnish authorities have recovered the anchor of the tanker Eagle S, which is suspected of damaging cables in the Baltic Sea. Investigators will inspect the anchor starting on Tuesday. Finnish radio Yle reported that the anchor of the tanker Eagle S was located at the bottom of the Gulf of Finland and brought to the surface.
