The latest launch was Pyongyang's fifth in 10 days, amid military muscle-flexing by the United States, South Korea and Japan. Last week, the three countries conducted trilateral anti-submarine exercises that included a U.S. aircraft carrier, which stopped in South Korea for the first time since 2017. The United States said it strongly condemned North Korea's "dangerous and reckless" decision to launch a long-range ballistic missile over Japan. South Korea's Joint Chiefs of Staff (JCS) said it appeared to have been an intermediate-range ballistic missile (IRBM) launched from North Korea's Jagang Province. North Korea has used that province to launch several recent tests, including multiple missiles that it claimed were "hypersonic."
