It appears that North Korea is signaling that they have cluster munitions just like Iran has used against Israel:

North Korea has tested cluster bombs in its latest launch of surface-to-surface ballistic missiles, supervised by leader Kim Jong-un, state media reported Monday.
The Korean Central News Agency (KCNA) published the report of the launch of the Hwasong-11 Ra tactical ballistic missile a day after South Korea’s military detected multiple short-range ballistic missiles launched toward the East Sea at around 6:10 a.m. from North Korea’s Sinpho area.
The KCNA said the purpose of the test-launch was to evaluate the power of the “cluster bomb warhead and fragmentation mine warhead” fitted to the weapon system.
