North Korea fires ballistic missile toward sea amid rising tensions with South

North Korea fired a ballistic missile from Wonsan on October 3, 2026, which flew over 700 kilometers before landing outside Japan's exclusive economic zone. The launch occurred amid high tensions following a September 21, 2026, land mine incident in the DMZ that injured South Korean soldiers. Kim Yo Jong rejected Seoul's demands for an apology as "utterly pathetic," while South Korea, Japan, and the United States coordinated intelligence sharing to monitor further military actions.
