Tensions have flared between the US and North Korea, with the dictatorship warning Washington is now on a "countdown toward confrontation".
North Korea issued the charged statement on Monday following what it called "reckless remarks" by US Secretary of State Mike Pompeo.
Pyongyang now believes the US has no intention of resuming nuclear talks, with a spokesman for leader Kim Jong Un vowing they will payback "the pains the US has imposed on our people" through sanctions.
It came after Mr Pompeo told reporters last week following a meeting of G7 leading industrial nation that the international community must remain united in urging North Korea to return to nuclear talks and to end its nuclear and missile programmes.
