It is North Korea's first public weapons test since the second US-North Korea summit in Hanoi ended with no agreement in February.

KCNA did not describe exactly what the weapon is, including whether it was a missile or another type of weapon, but "tactical" implies a short-range weapon, as opposed to the long-range ballistic missiles that have been seen as a threat to the United States.

Nevertheless, the missile has a "peculiar mode of guiding flight" and "a powerful warhead," KCNA said.

Kim said "the completion of the development of the weapon system serves as an event of very weighty significance in increasing the combat power" of the North Korean army, according to KCNA.

Last year, Kim had also overseen a test of an unidentified "tactical weapon" in November, according to state media, which could protect North Korea like a "steel wall".

Last year, Kim had said North Korea will stop nuclear tests and launches of intercontinental ballistic missiles, because Pyongyang's nuclear capabilities had been "verified."

The news of Kim's visit to the tactical weapon testing site comes after the North Korean leader visited the North Korean Air and Anti-aircraft Force on Tuesday, according to KCNA, inspecting a flight drill and expressing "great satisfaction" at their combat readiness.

Meanwhile, satellite images from last week show movement at North Korea's main nuclear site that could be associated with the reprocessing of radioactive material into bomb fuel, the Centre for Strategic and International Studies in the United States said on Tuesday./.
