North Korea had launched several short-range ballistic missiles, flying about 400 kilometers (249 miles).
The purpose of the test launch was to confirm the accuracy of hitting a target with a super-large warhead at a distance of up to 320 kilometers (200 miles) and assessing the warhead's explosive power, according to the state-run KCNA news agency.
