Pyongyang, April 20 (QNA) - North Korea fired the Hwasong-11 Ra surface-to-surface tactical ballistic missile in a recent test launch attended by leader Kim Jong-un to evaluate the missile's warhead capability, Pyongyang's state media reported Monday.

The Korean Central News Agency (KCNA) published the report a day after South Korea's military detected multiple short-range ballistic missiles launched toward the East Sea 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.

Five missiles struck a target area near an island about 136 kilometers away with "very high density," fully demonstrating their combat capability, the KCNA report said.

Kim expressed "great satisfaction" over the test-launch, saying, "It is of weighty significance ... to boost the high-density striking capability to quell a specific target area, as well as the high-precision striking capability," according to (Yonhap) news agency.

The North Korean Leader also encouraged science research groups responsible for weapons development, expressing hope that they would continue their "important undertakings to acquire and update various ultra-modern technologies necessary for the combat preparedness of our army."

Sunday's launch followed the North's test-firing of multiple short-range ballistic missiles on April 8. State media said at the time the country test-fired a tactical ballistic missile tipped with a cluster bomb warhead, claiming it could "reduce to ashes any target" within its range with the highest-density power.

South Korea's Office of National Security has condemned the latest North Korean missile launch as a violation of UN Security Council resolutions and called for an immediate halt to the North's missile provocations. (QNA)
