Approximately 95 percent of the world's data is transmitted via over 500 cables that span the ocean floor. In recent months, these crucial links have been targeted in several attacks.

They added: "Subsea cable security must be a cornerstone of broader infrastructure protection efforts. By acting now, we can safeguard the networks that underpin our shared future." Meanwhile, Vladimir Putin threatens "worldwide blackouts" as NATO issues a chilling warning.

In their letter, they stated: "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."

Executives from companies such as Vodafone, Orange, and Telefonica have penned an open letter to the UK, EU, and NATO, warning that Russia could easily destroy or disrupt the "defenseless" cables following a series of attacks.

NATO is concerned that the Kremlin could unleash a new weapon against the world, causing "worldwide blackouts" by sabotaging undersea cables with its "shadow fleet".
