N.Korea: Kim Jong Un oversees test launch of submarine-launched cruise missiles

North Korea says its leader Kim Jong Un has overseen the test firing of submarine-launched cruise missiles.

North Korea's ruling Workers' Party newspaper, Rodong Sinmun, reported on Monday that the test-firing of the Pulhwasal-3-31, a new type of strategic cruise missile, was conducted on Sunday. Pulhwasal means "blaze arrow" in Korean.

The newspaper said the missiles flew above the sea off the country's east coast for over two hours before hitting an island target.

It did not say whether the cruise missiles were actually launched from a submarine. The newspaper carried images of a missile billowing smoke, flying over the sea.

The newspaper said Kim expressed great satisfaction over the result of the test. It went on to say the leader gave instructions on realizing a navy with nuclear weapons and diversifying nuclear deterrence.

South Korea's military reported on Sunday that the North fired several cruise missiles in waters off the eastern port city of Sinpho. Pyongyang's announcement on Monday is believed to be about those missiles.

The Rodong Sinmun also reported that Kim discussed issues related to building a nuclear-powered submarine.

The latest firing of cruise missiles follows one last week. They are expected to be able to carry a tactical nuclear warhead.
