The leader of the UK's armed forces warned that Russian submarine activity is threatening underwater cables that are crucial to communication systems around the world - and that cutting these cables would be an "act of war".

Admiral Sir Tony Radakin described the undersea cables as "the world's real information system" explaining that they transmit internet data and that damaging them could declare war.

I would say that cutting those cables is indeed an act of war.

Damaging a cable should be criminal and punishable by death!

I agree that it appears to be "an act of war." How rude!

Quote your actual source. I can find nothing aside from "threats" that Russia could do it.

They have not.

They did the same thing 6 years ago(2015).

This is a NON-story, but I can see why you'd like it, since the source is from one of the most unreliable outfits out there and it's a heavily right-wing British rag.
