Kerry to North Korea: We'll Take 'Appropriate Action'

John Kerry is warning North Korea that the U.S. will take “appropriate action” in response to the rogue nation’s “latest nuclear test.”

“The United States and nations around the world have unequivocally condemned North Korea’s latest nuclear test. This highly provocative act poses a grave threat to international peace and security and blatantly violates multiple U.N. Security Council resolutions,” Kerry says in a statement released by the State Department.
