North Korea said Tuesday it has put its military on combat ready status, with "strategic" rocket units and long-range artillery units ordered to prepare for possible strikes against the U.S. mainland, Hawaii and Guam, the state media reported.

The order issued in a statement from the North Korea’s “supreme command" came after the U.S. bombers flew sorties threatening the North, Reuters reported.

"From this moment, the Supreme Command of the Korean People's Army will be putting into combat duty posture No. 1 all field artillery units, including long-range artillery units and strategic rocket units, that will target all enemy objects in the U.S. invasionary bases on its mainland, Hawaii and Guam," the Korean Central News Agency said.

Apparently, North Korea’s supreme leader Kim Jong Un has ordered the army to destroy and wipe away any enemy who lands on their coast.

The threat is the latest in the series of war rhetoric from the North Korea against the U.S. and South Korea since the joint military drills by the allies and extension of economic sanctions by the U.N. Security Council. The North in response to the ongoing military drills had said it scrapped 1953 armistice that stopped the Korean War.

Pyongyang had earlier threatened to use nuclear warheads against the U.S. and South Korea. Although the North has the technology to hit targets in the South and neighboring regions with nuclear weapons, it apparently does not have the capability to strike the continental United States.

However, the U.S. military bases in the Pacific area are in the range of the North’s midrange missiles, Reuters reported.

Meanwhile, South Korean authorities said they have not observed any unusual activities by the North’s military, but said they are closely monitoring the situation.
