North Korea on Friday said it has test-launched a new type of anti-ship cruise missile with the power to strike U.S. and South Korean warships.

The missiles are the fourth new missile system North Korea has disclosed and tested this year.

"This new-type cruise rocket is a powerful attack means capable of striking any enemy group of battleships" attempting to attack North Korea and can be used "at will," the North's official Korean Central News Agency said.

The agency said leader Kim Jong Un observed the launches and that the missiles "accurately detected and hit" floating targets. These claims could not be independently confirmed.

South Korean national security director Chung Eui-yong said later Friday "the North" had fired four short-range missiles on Thursday. 

The launch came days after U.S. aircraft carriers USS Carl Vinson and USS Ronald Reagan left those waters after joint exercises with the South Korean navy.
