North Korean leader Kim Jong-un has overseen a test-fire of a 240mm multiple rocket launcher with a new guidance system, Yonhap News Agency reports citing the state media.

Kim attended Tuesday's test of the multiple rocket launch system (MRLS) that is produced at defense industrial enterprises under the Second Economic Commission, according to the Korean Central News Agency (KCNA).

The weapon could put Seoul and its adjacent areas in target range.

"The MRLS, technically updated in its maneuverability and concentrated firing capability, was proved to be advantageous in all indices, including newly applied guiding system, controllability and destructive power," the KCNA said.

Kim "set forth an important policy to be pursued in producing new artillery pieces and equipping army units with them," it added, without providing further details.

In February, North Korea said it had newly developed "controllable" 240mm rocket launcher shells, a move that could boost its weapons capabilities with improvements in range and precision. In May, the country said it will deploy the weapon system to Korean People's Army units between 2024 and 2026.
