North Korea said on Monday that it carried out successful long-range cruise missile tests over the weekend.

The North's official Korean Central News Agency(KCNA) said on Monday that the country successfully test-fired a new type of long-range cruise missile on Saturday and Sunday. 

The state-run mouthpiece said the missiles flew 15-hundred kilometers for about two hours before hitting their targets and falling into the country's territorial waters in the tests conducted by the Academy of National Defense Science.

The report claimed the development of the missiles provides strategic significance as it shows another effective deterrence that more reliably guarantees national security and strongly contains the military maneuvers of hostile forces.

The latest launches were reportedly led by senior officials including Pak Jong-chon, member of the Presidium of the ruling Workers' Party. North Korean leader Kim Jong-un did not oversee the tests.
