NORTH Korea has declared it has given 'final approval' for a nuclear attack on the United States.
AFP is reporting the declaration, which came minutes after the United States announced it would deploy a land-based missile defence system to Guam to counter North Korean threats of a nuclear strike.
The United States Department of Defense has issued a statement saying a truck-mounted launcher and radar system will be moved to Guam in next few weeks.
The missile system joins two destroyers deployed to the region in the past few days. The ships are also capable of intercepting intercontinental ballistic missile.
