NKorea says new ICBM puts US in range

North Korea says it has successfully tested a new, nuclear-capable intercontinental-ballistic missile that could target the entire US mainland.

The North's state television said on Wednesday the new ICBM was "significantly more" powerful than the previous long-range weapon the North tested.

The report called the weapon a Hwasong 15.

It also says it has "realised (the) great historic cause of completing (the) state nuclear force".
