The US said a ballistic missile exploded within seconds of launch.

Hours earlier, North Korea paraded what appeared to be long-range ballistic missiles at a major military display.
According to the report, North Korea has already conducted five nuclear tests and a series of missile launches in contravention of UN resolutions.
The latest development came as US Vice-President Mr. Mike Pence, arrived in the South Korean capital, Seoul, where he was expected to discuss the best way to deal with North Korea’s missile and nuclear programmes.
The US Pacific Command later confirmed the failed test, adding that it had detected and tracked what it believed to be a North Korean ballistic missile.
