Evacuations after reports of white phosphorus leak at US air base in South Korea

South Korea evacuated residents after what they described as a white phosphorus leak at a US military base near the capital, Seoul on Tuesday.White phosphorus is a controversial chemical substance used in incendiary munitions and smoke shells. When ignited, it burns at extremely high temperatures and can set buildings ablaze and burn human flesh to the bone.

Officials in the city of Pyeongtaek urged nearby residents to move to a safe location and avoid skin exposure after the leak was detected at around 5 p.m. at the Osan Air Base.

They lifted the evacuation order several hours later, saying decontamination work at the base had been completed, according to text messages sent out by the city.Police reportedly used vehicles to establish a perimeter 300 to 500 meters (yards) from the base, blocking pedestrians and rerouting vehicles. There were no immediate reports of major disruptions or accidents.
