N.Korea Threatens Preemptive Strike Against U.S.

North Korean Foreign Minister Ri Su-yong on Tuesday warned that Pyongyang has the power to deter the "ever-increasing nuclear threat" from the U.S. with a preemptive strike.

In a rare speech in front of the UN Conference on Disarmament, Ri said joint military exercises being staged by South Korea and the U.S. are "unprecedentedly provocative in nature and have an especially high possibility of sparking off a war."

Ri added that the North now "has the power of deterring the U.S. and conducting a preemptive strike as well, if necessary."
