Russia could cut off internet to Nato countries, British military chief warns

Russia could pose a major threat to the UK and other Nato nations by cutting underwater cables essential for international commerce and the internet, the chief of the British defence staff, Sir Stuart Peach, has warned.

Russian ships have been regularly spotted close to the Atlantic cables that carry communications between the US and Europe and elsewhere around the world.

Air Chief Marshall Peach, who in September was appointed chair of the Natomilitary committee, said Russia had continued to develop unconventional warfare. He added that threats such as those to underwater cables meant the UK and its allies had to match the Russian navy in terms of modernising its fleet.

“There is a new risk to our prosperity and way of life, to the cables that crisscross our sea beds, disruption to which through cable-cuts or destruction would immediately – and catastrophically – fracture both international trade and the internet,” he said.
