North Korea tensions

North Korea says missile could carry nuclear warhead

The country's leader, Kim Jong Un, supervised the launch of the Hwasong-12 missile that reached an altitude of 2,111.5 kilometers (1,312 miles) and flew 787 kilometers (489 miles), KCNA said.

The test was "aimed at verifying the tactical and technological specifications of the newly developed ballistic rocket capable of carrying a large-size heavy nuclear warhead," KCNA said.

North Korea warned the United States not to provoke it, saying the "US mainland and Pacific operations" are within range of North Korean missiles, KCNA said.
