North Korea says Kim Jong-un supervised missile test targeting Seoul

North Korea has described some of the systems it tested as capable of delivering tactical nuclear warheads to South Korea's capital.

North Korean leader Kim Jong-un supervised a live-fire drill of nuclear-capable “super-large” multiple rocket launchers designed to target South Korea's capital as he vowed to boost his war deterrent in the face of deepening confrontations with rivals, state media said Tuesday.

The report came a day after South Korea and Japan said they detected North Korea firing multiple short-range ballistic missiles toward waters off its eastern coast, adding to a streak of weapons displays that have raised regional tensions.

Experts say North Korea’s large-sized artillery rockets blur the boundaries between artillery systems and ballistic missiles because they can create their own thrust and are guided during delivery. The North has described some of these systems, including the 600 mm multiple rocket launchers that were tested Monday, as capable of delivering tactical nuclear warheads.

Photos published by the North’s official Korean Central News Agency showed at least six rockets being fired simultaneously from launch vehicles and flames and smoke blanketing what appeared to be a small island target.

South Korea's Joint Chiefs of Staff said later Tuesday that it assesses North Korea conducted more launches than what was shown on the photos. Lt. Col. Lee Chang-hyun, a deputy JCS spokesperson, said that South Korea categorizes the North Korean weapons system tested Monday as a ballistic missile in view of its characteristics and capacities.
