South Korea’s military said North Korea launched a ballistic missile toward the sea off its east coast on Saturday, in the latest sign of heightened tensions on the Korean Peninsula.

Officials in Seoul said they were maintaining a readiness posture while they continued to assess the launch and gather additional details. The report did not immediately identify the missile type or provide information on how far it traveled.

Ballistic missile tests by North Korea often trigger rapid responses from South Korea and its allies, who monitor the region closely for signs of further escalation. The launch comes amid persistent concern over Pyongyang’s weapons program and its impact on regional security.

No casualties or damage were reported in the initial account. Reuters said it was continuing to follow the situation.
