Seoul: No white phosphorus has been found at the U.S. Osan Air Base in Pyeongtaek, the U.S. Forces Korea (USFK) stated, following an emergency alert issued in the region over a suspected white phosphorus leak at the base.

According to Yonhap News Agency, the USFK disclosed the findings on the Osan Air Base website after the Pyeongtaek city government issued an alert on July 28. This alert informed the public of a potential white phosphorus leak at the base, following a report from the U.S. military.

"Following thorough inspection and testing, we can confirm that the crystallization and residue identified during a routine munitions inspection on July 28 was not white phosphorus nor contained traces of white phosphorus," the USFK reported.

The statement further clarified that after follow-on analysis, the residue was determined to be non-hazardous surface corrosion resulting from environmental exposure over time.

Emergency response professionals acted promptly to ensure full containment of the munitions, and base operations are continuing as normal, with no injuries reported, the USFK also noted.

"We deeply value the trust of our Pyeongtaek neighbors and are committed to keeping everyone safe, informed, and updated," the statement added.
