(CNN) -- North Korea said Sunday's test-fire of a ground-to-ground ballistic missile proved the missile is capable of carrying a large nuclear warhead, state news agency KCNA said in a report Monday.
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. That's higher and closer to Russia than other North Korean tests, according to US officials.
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.
