South Korea's Joint Chiefs of Staff launched an investigation into a near-shootdown incident involving a U.S. military reconnaissance drone Tuesday morning in restricted airspace approximately 10 kilometers south of the Demilitarized Zone. A radar lock-on by an unidentified ground-based system triggered defensive maneuvers by the U.S. aircraft, though no shots were fired. The close call represents a serious breach of established air safety protocols in the heavily militarized region.

The incident escalates already high tensions on the Korean Peninsula, where North Korea has conducted 14 missile tests this year, including several near the border. U.S. Forces Korea maintains 28,500 troops in the country under a mutual defense treaty, conducting regular surveillance missions. The near-miss could prompt a significant reassessment of joint operational protocols and intelligence sharing between Seoul and Washington.

A spokesperson for the U.S. Indo-Pacific Command confirmed the incident, saying the drone returned to base safely and without damage. South Korea's Ministry of National Defense declined public comment on the origin of the radar signature, citing an ongoing review. High-level consultations between U.S. and South Korean defense officials began within hours. Gen. Paul LaCamera, commander of U.S. Forces Korea, met with South Korean Defense Minister Lee Jong-sup to discuss the sequence of events.

The U.S. State Department has reportedly requested full access to South Korea's radar data from the incident, seeking clarity on the source of the radar lock. Both nations expect to conclude their initial reviews within two weeks, with findings expected to inform future security dialogues. A joint U.S.-South Korean working group is expected to convene next month to address the findings and propose revised operational guidelines.
