North Korea missile test ends in failure - Seoul

Earlier this month North Korea fired four ballistic missiles that landed in waters off Japan, triggering strong protests from Seoul and Tokyo.

A new missile launch by North Korea appears to have ended in failure, South Korea has said, three days after Pyongyang claimed a major breakthrough in its rocket development programme.

The reported launch failure came as US and South Korean troops were conducting their annual military drills that the North calls an invasion rehearsal.
