North Korea says its strategic rocket and long-range artillery units have been ordered to enter combat mode targeting US military bases on Guam, Hawaii and mainland America after US bombers flew more sorties threatening the country.
"From this moment, the Supreme Command of the Korean People's Army will be putting in combat duty posture No 1 all field artillery units including long-range artillery units strategic rocket units that will target all enemy object in US invasionary bases on its mainland, Hawaii and Guam," Pyongyang's KCNA news agency said.
The order, issued in a statement from the North's military "supreme command", marks the latest fiery rhetoric from Pyongyang since the start of joint military drills by US and South Korean forces early this month.
South Korea's defence ministry said it saw no sign of imminent military action by North Korea.
North Korea previously threatened a nuclear attack on the US and South Korea, although it is not believed to have the technology to hit the continental US with an atomic weapon. But the US military's bases in the Pacific area are in range of its medium-range missiles.
South Korea's defence ministry said it had detected no signs of unusual activity by the North's military but will monitor the situation. The South and the US military are conducting drills until the end of April, which they have stressed are strictly defensive in nature.
The North has previously threatened to strike back at the US military, accusing Washington of war preparations by flying B-52 bombers over the Korean peninsula as part of the drills.
In the past few weeks, North Korea has said it has abrogated an armistice that halted the 1950-53 Korean war and threatened a nuclear attack on the US.
