South Korea said on Saturday that North Korea fired a ballistic missile toward the East Sea, in the latest sign of heightened military tension on the Korean Peninsula. Seoul’s military said it was tracking the launch and collecting further details.

Officials in South Korea and the United States were analyzing the flight and other technical information after the test, which comes amid long-running concerns over Pyongyang’s missile program and its impact on regional security. No immediate damage or casualties were reported.

The launch adds to a pattern of weapons demonstrations by North Korea that have drawn condemnation from neighboring governments and raised alarm over the risk of escalation. Such tests also complicate diplomatic efforts to reduce tensions and restart talks on denuclearization and arms control.

South Korea’s military said it would continue monitoring North Korean activity closely. The latest launch is likely to renew calls for tighter deterrence and closer coordination between Seoul and Washington.
