North Korea said it tested a cluster-bomb warhead for tactical ballistic missiles on Saturday, and South Korea's military said it tracked a related launch toward the Yellow Sea from the northwest, Yonhap reported citing Korean Central News Agency and the Joint Chiefs of Staff¹.

KCNA said the Missile Administration ran the test to assess combat adaptability and power of a warhead meant for tactical ballistic missiles¹. State media said research institutes concluded that a Standard Type 2 cluster-bomb warhead could cover a target area of 12 to 13 hectares¹.

A Missile Administration director said cluster-bomb warheads are grouped into four categories by purpose and that units would be able to select those types by the end of the year, Yonhap reported¹. Cluster munitions release many submunitions over a wide area¹.

South Korea's Joint Chiefs of Staff said Sunday that it had monitored the activity and that a missile was fired toward the Yellow Sea from around Chongju, with information shared with the United States¹. Shin Jong-woo of the Korea Defense and Security Forum said the missile appeared to be the Hwasong-11 Ra¹. North Korea said in April that it had tested cluster bombs on that missile type¹.

The Saturday test came after South Korea, the United States and Japan restated a denuclearization goal in Atlanta talks, Yonhap reported, and after U.S. Secretary of State Marco Rubio said President Donald Trump remained open to talks with Kim Jong-un if Pyongyang would discuss issues of concern to Washington and its allies¹.

On Oct. 29, South Korea's military said North Korea fired short-range ballistic missiles toward the East Sea from the Wonsan area at about 12:30 p.m.^6,7,11. Counts in those reports ranged from about 10 to around a dozen^6,7,11,17. Yonhap and France 24 said Seoul put the flight distance at about 250 kilometers^7,11.

Japan's Defense Ministry said a suspected ballistic missile splashed down outside Japan's exclusive economic zone^14,6,13. Early Seoul bulletins described an unidentified projectile before later statements specified multiple short-range ballistic missiles^18,19,16.

Yonhap and France 24 tied the Oct. 29 salvo to a border dispute after a Sept. 21 land-mine blast that wounded three South Korean soldiers and to Seoul's subsequent offer of military talks^7,11. Seoul's National Security Office called those launches a violation of U.N. Security Council resolutions, France 24 reported⁷. Independent confirmation of KCNA's cluster-warhead performance claims was not in the South Korean statement¹.
