SEOUL, South Korea (AP) — North Korea has fired an intermediate-range ballistic missile over Japan for the first time in five years as it escalates tests of weapons designed to strike regional U.S. allies. The launch early Tuesday forced Japan to issue evacuation notices to residents in the northeast and suspend trains. It was North Korea’s most significant missile test since January. Japan and South Korea both called security meetings to discuss the launch. The launch is the fifth round of weapons tests by North Korean in the past 10 days in what was seen as an apparent response to recent military drills involving the United States and its allies in North Asia.
