North Korea said Wednesday it had conducted a ballistic missile test that simulated preemptive strikes against South Korean ports and airfields used by the U.S. military, a likely reference to the launches of three missiles on Tuesday.
The North's leader, Kim Jong Un, supervised the exercise that successfully tested the simulated detonation of nuclear warheads mounted on missiles, the official KCNA news agency reported.
It did not give the date of the exercise, as it customarily reports activities of its leader without dates or locations. Rodong Sinmun, the ruling Workers' Party's official newspaper, carried photographs of Kim with military aides, apparently observing a ballistic missile exercise.
