SEOUL—Analysts and security officials say they are watching for signs that North Korea may use an upcoming holiday to unveil new weapons or test fire a submarine-launched ballistic missile (SLBM), after a flurry of activity was detected at a key base.
Formations of troops have been seen practicing for what is expected to be a major military parade on Oct. 10, the 75th anniversary of the ruling Workers’ Party of Korea. Some observers say North Korea may showcase its largest missiles for the first time since 2018.
