North Korea today warned ‘the moment of explosion is near' as it declared that troops have been cleared to attack the U.S. using 'smaller, lighter and diversified' nuclear weapons.
The rogue state has moved a missile with a range of 3,000km (1,800m) to its east coast - within range of Japan - and claimed it would be ‘merciless’ against its enemies.
Kim Jong Un’s dramatic deployment came after the U.S. announced it was sending ballistic missile defenses to Guam - the tiny Pacific Island on a list of possible targets for attack including Hawaii.
Today the United States also deployed a battalion of anti-nuke and biological warfare soldiers in a show of strength on the Korean peninsula.
Its display at a base north of Seoul came on a day of growing concern about the threat posed by the secretive communist state.
