Britain has reportedly practiced a cyberattack to send Moscow into total blackout

British military forces reportedly practiced a cyberattack on Russia on Saturday to send Moscow into total darkness if Vladimir Putin's forces attack the West.

Military sources told the Sunday Times that the only other way of hitting Russia back would be to use nuclear weapons.

But cyber weapons reportedly give Britain the best chance of deterring Russia because the West no longer has small battlefield nuclear weapons.

The Sunday Times reported that the test to "turn out the lights" in Moscow - which will give Britain more time to act in the event of war - happened during the UK's biggest military exercise for a decade.
