North Korea tests cluster warheads

The launches involved upgraded short-range ballistic missiles, including the Hwasongpho-11 Ra, which were tested for accuracy and destructive power.

This marks the fourth ballistic missile test in April and the seventh of the year, underscoring Pyongyang's rapid pace of weapons development.

Analysts suggest the use of cluster munitions is intended to increase the lethality of strikes against ground targets and military installations.

The tests have drawn condemnation from South Korea and the United States, who are currently conducting large-scale military exercises in the region.
