Kim Jong-un says North Korea ready to test nuclear warhead

Claim is latest in increasingly belligerent round of threats following North Korea's nuclear test earlier this year

Kim Jong-un said North Korea would soon conduct a nuclear warhead explosion test and a test launch of ballistic missiles capable of carrying nuclear warheads, the official KCNA news agency reported on Tuesday.

Mr Kim made the comments as he supervised a successful simulated test of atmospheric re-entry of a ballistic missile, KCNA said.
