North Korea has tested a newly developed lightweight multipurpose missile launching system and multiple tactical cruise missiles, state media said Wednesday, with leader Kim Jong-un overseeing the test as part of Pyongyang's ongoing weapons modernization drive.

The Korean Central News Agency (KCNA) published the report a day after South Korea's military detected the launch of multiple close-range ballistic missiles (CRBMs) and artillery rockets toward the Yellow Sea from the Jongju area of North Phyongan Province.

CRBMs refer to ballistic missiles that have a relatively short range of less than 300 kilometers.

Tuesday's test was "part of the plan for modernizing the artillery and missile armed forces to attain the five-year goal for national defense development," the KCNA report said.
