The latest missile test by North Korea was of "a new-type ground-to-sea cruise rocket," the nuclear-armed country's state media said Friday.

The North's official Korean Central News Agency said that Thursday's launches were of "a powerful attack means capable of striking any enemy group of battleships attempting at military attack on the DPRK from the ground at will."

DPRK is the acronym for the North's formal name, the Democratic People's Republic of Korea.
