The Missile Administration of the Democratic People's Republic of Korea (DPRK) on Monday successfully tested a new type of tactical ballistic missile "capable of carrying a 4.5-ton super-large warhead," the official Korean Central News Agency (KCNA) reported on Tuesday.

It reported the test of the new tactical ballistic missile, which it said was named Hwasongpho-11 Da-4.5, was conducted with a simulated heavy warhead to verify flight stability and accuracy.

The country's missile administration will conduct another launch of the same type of missile in July, according to KCNA.

A day earlier, South Korea reported the launch of two ballistic missiles by the DPRK and said the second likely failed soon after launch, blowing up in flight over land.

KCNA made no mention of a second missile.
