The announcement comes as Australian Prime Minister Julia Gillard and Foreign Minister Bob Carr head to China tomorrow to urge Beijing to take stronger action against its ally North Korea, reports The Herald.

North Korea alarmed the world by announcing it was ready to launch a nuclear strike at the US, with the Korean People’s Army general staff saying “The moment of explosion is approaching fast.”

The statement was in response to what it called provocative US use of nuclear-capable B-52 and B-2 stealth bombers. The US aggression would be “smashed by … cutting-edge smaller, lighter and diversified nuclear strike means,”it added.
