North Korea had conducted a power test of a super-large warhead designed for "Hwasal-1 Ra-3" strategic cruise missile and a test launch of "Pyoljji-1-2" new-type anti-aircraft missile on Friday afternoon, it reported, citing the DPRK Missile Administration. North Korea's strategic cruise missile is believed to be designed to carry a nuclear warhead.

"Both tests were part of the regular activities of the administration and its affiliated defence science institutes for the rapid development of technologies in various aspects such as tactical and technical performance and operation of new-type weapon systems," KCNA reported, adding that they were not related to the regional situation.
