Russia's new Skyfall missile will be able to fly around Earth for years and launch a nuclear strike at any moment, Britain's defence intelligence chief has warned.
The 9M730 Burevestnik missile, also known as Skyfall by Nato, has been linked to the deaths of at least five scientists in an accident in Nyonoksa, north eastern Russia, that caused a radiation spike 'one thousand times higher than lethal,' last August.
Britain's Chief of Defence Intelligence, Lt Gen Jim Hockenhull, told a media briefing: 'Moscow is testing a subsonic nuclear-powered cruise missile system which has global reach and would allow attack from unexpected directions'.
