Since early last year, the North has been on a quick succession of missile-related activities, claiming major advances that outside experts and officials believe may be at least partially true but are difficult to verify independently.

Hwasong, or Mars, in Korean, is the North’s name for its Scud-class ballistic missiles.

The North’s official media routinely report on missile launches on the following day.

The test was aimed at verifying a new type of precision guidance system and the reliability of a new mobile launch vehicle under different operational conditions, KCNA said.

“Whenever news of our valuable victory is broadcast recently, the Yankees would be very much worried about it and the gangsters of the south Korean puppet army would be dispirited more and more,” KCNA quoted Kim as saying.
