Finnish police have reported finding the anchor responsible for severing an undersea internet cable connecting Finland to Estonia. Last month, Finland detained the Eagle S, an oil tanker transporting Russian oil,

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