South Korean authorities ordered civilians to evacuate Tuesday after a suspected white phosphorus leak at the U.S. Osan Air Base near Seoul. Officials in Pyeongtaek urged nearby residents to move to a safe location and avoid skin exposure after the leak was detected around 5 p.m. The alert was lifted several hours later following the completion of decontamination work. The U.S. 51st Fighter Wing stated it established a 300-meter cordon around the base out of caution after experts identified white phosphorus crystallization inside a munitions crate. An explosive ordnance disposal unit was deployed to ensure containment. The base commander stated there were no injuries and no risk to personnel. White phosphorus is a controversial chemical used in incendiary munitions that burns at extremely high temperatures.
