NATO is ready to help Finland and Estonia as Finnish authorities probe an oil tanker that sailed from a Russian port over the possible "sabotage" of a power cable linking the two member countries, alliance chief Mark Rutte has said.
"Spoke with (Estonian Prime Minister) Kristen Michal about reported possible sabotage of Baltic Sea cables. NATO stands in solidarity with Allies and condemns any attacks on critical infrastructure.
"We are following investigations by Estonia and Finland, and we stand ready to provide further support," Mr Rutte said on X.
Earlier, Finnish authorities said they were investigating an oil tanker that sailed from a Russian port for the "sabotage" of a power cable linking Finland and Estonia that was damaged the previous day.
The Cook Islands-registered ship, named by authorities as the Eagle S, was boarded by a Finnish coast guard crew which took command in the Baltic Sea and sailed the vessel to Finnish waters, a coast guard official told a press conference.
"From our side we are investigating grave sabotage," Robin Lardot, Director of the Finnish National Bureau of Investigation, said.
"According to our understanding an anchor of the vessel that is under investigation has caused the damage," he added.
Well, this was a power cable this time, not a communication cable.
As for your idea, atmospheric distortion makes lasers not viable beyond a certain distance. Even on a crystal clear day the light would be too distorted/spread out to be useful beyond a few miles. The cables use fiber optic, which mitigates the distortion problem, but still requires repeaters to boost the signal every 100 kilometers or so.
