US warns N Korea missile launch would be 'huge mistake'

US Secretary of State John Kerry has said an anticipated missile launch by North Korea would be a "provocative act" and "huge mistake".

But he played down a US report that the North has a nuclear warhead, saying it was "inaccurate" to suggest it has "a working and tested" device.
