The anchor of the Eagle S oil tanker has been recovered from the bed of the Baltic Sea during an inquiry into the ship's possible involvement in sabotage of maritime energy and communication cables. The EU says the tanker belongs to the so-called Russian shadow fleet.

Finland's public transport agency said on Wednesday that an oil tanker suspected of damaging undersea cables in the Baltic Sea was found to have serious deficiencies and will not be allowed to operate until repairs have been made.

Police in Finland are investigating what they called "grave sabotage" and have taken command of Eagle S, an oil tanker believed to belong to a so-called shadow fleet of ageing tankers which seek to evade Russian sanctions.
