North Korea says it is "carefully examining" a plan to strike the US territory of Guam with missiles.
The threat came hours after President Donald Trump told Pyongyang that any threat to the US would be met with "fire and fury".
A spokesman for the Korean People's Army said the strike plan would be "put into practice in a multi-current and consecutive way any moment" once Kim Jong Un makes a decision.
He added that "enveloping fire" would be used to contain major US military bases on the island territory in the western Pacific Ocean - including the Anderson Air Force Base.
KCNA, Pyongyang's state-run news agency, also carried a statement from a different military official which said North Korea may carry out a pre-emptive operation if the US shows signs of provocation.
