North Korea has said it is proceeding with plans for a third nuclear test, two days after the UN Security Council condemned Pyongyang's recent rocket launch.

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.
