Military chiefs at Nato have been warned of global internet blackouts following a string of suspected Russian attacks on subsea cables.

Telecoms companies including Vodafone, O2 owner Telefonica and Orange have written to UK, EU and Nato officials warning that a rise in sabotage incidents was putting critical services at risk.

In an open letter, they wrote: “The repercussions of damage to subsea cables extend far beyond Europe, potentially affecting global internet and power infrastructure, international communications, financial transactions and critical services worldwide.”

It comes after a spike in incidents relating to fibre optic cables on seabeds that carry huge volumes of data, voice and internet traffic between countries.
