North Korea says it has approval to use its 'cutting edge' nuclear weapons against America in a 'merciless' attack hours after U.S. warns of 'clear and present danger'

The North Korean Army said today it had received final approval to launch 'merciless' nuclear strikes against the United States.
It said it was formally notifying Washington that U.S. threats would be 'smashed by... cutting-edge smaller, lighter and diversified nuclear strike means,' according to a statement published by the official KCNA news agency.
'The merciless operation of (our) revolutionary armed forces in this regard has been finally examined and ratified.
'The moment of explosion is approaching fast,' the statement read, adding that it could occur 'today or tomorrow.'
Today it was reported that North Korea had moved what appears to be a mid-range Musudan missile to its east coast, according to South Korea's Yonhap news agency, quoting multiple government sources privy to intelligence from U.S. and South Korean authorities.
The missile is believed to be able to cover 1,875 miles - putting all of South Korea and Japan within range.

The pronouncement from the North Korean Army came just hours after U.S. Defence Secretary Chuck Hagel said North Korea presented a 'clear and present danger' to the U.S. and its allies after days of escalating rhetoric.
American troops in South Korea have been placed on high alert and are 'poised to respond' as tensions on the border between North Korea and its neighbor stretch to breaking point.
Having bolstered their already substantial forces in the region with B-2 Stealth Bombers, F-22 Stealth Fighters and B-52 heavy bombers, the U.S. is now dispatching a high-tech missile battery to Guam to protect the U.S. and its allies in the region in response to increasingly hysterical rhetoric from North Korea.
Hawaii and Guam would also be outside the range of its medium-range missiles, but U.S. bases in South Korea and Japan may be vulnerable.
Hagel issued a statement after U.S. stealth bombers were seen patrolling the border between North and South Korea as part of military exercises which have inflamed tensions in the region.
Despite a successful long-range rocket launch in December, it is believed North Korea is years from developing an inter-continental ballistic missile that could strike the mainland United States.
