North Korea has test-fired a new weapons system that it claims will boost the nation’s nuclear weapons capabilities, the state-run Korean Central News Agency (KCNA) reported early Sunday local time.

The test launch was observed under the supervision of North Korean leader Kim Jong Un and was commanded by the Ministry of National Defense, according to KCNA.

“The new-type tactical guided weapon system … is of great significance in drastically improving the firepower of the frontline long-range artillery units and enhancing the efficiency in the operation of tactical nukes of the DPRK,” the news outlet said. DPRK stands for North Korea’s official name, the Democratic People’s Republic of Korea.

“The test-firing proved successful,” it added.

KCNA did not say when the latest launch took place, but state media typically reports on such activities a day later, Reuters noted.

This is a breaking news story. It will be updated as more information becomes available.
