In a statement carried by KCNA news agency, the top military body said the “high-level nuclear test” and more long-range rocket launches were aimed at its “arch-enemy”, the US.
The statement gave no time-frame for the test. North Korea has conducted two nuclear tests, in 2006 and 2009.
The move comes two days after a UN Security Council resolution condemned Pyongyang’s recent rocket launch.
