South Korean officials in the city of Pyeongtaek say they tried to reach the U.S. military through a hotline after a possible chemical leak was reported at a nearby air base, but their calls went unanswered. The incident, which triggered a short-lived evacuation alert last month, has raised questions about the effectiveness of the emergency communication channel between the host city and U.S. forces.

The South Korean government is also in talks with the U.S. military to gain access to the K-55 Osan Air Base for safety inspections, according to sources with knowledge of the matter, as reported by Yonhap News Agency.

Coverage Comparison

Two separate reports from Yonhap News Agency describe the sequence of events from slightly different angles. The first report, published in late July, focused on the South Korean government's efforts to arrange an inspection of the base following the reported leak. The second, published in mid-August, centered on the Pyeongtaek city government's failed attempts to reach the U.S. military via a hotline during the emergency.

While the initial report stated that the U.S. military had reported a leak of white phosphorus residue at the base, a later statement from the U.S. military contested that characterization, saying the substance was not white phosphorus. The contradiction remains unresolved in the available reporting.

Key Claims

  • The South Korean government is in talks with the U.S. military to conduct environmental inspections at Osan Air Base, following the reported leak. A government official said discussions were ongoing, and another official said air quality monitoring would be conducted near the site to ensure no safety hazards for residents.
  • The 51st Fighter Wing at Osan Air Base discovered a possible leak of white phosphorus residue inside a munitions crate during a routine inspection on July 28, according to a statement from the wing. The amount leaked was not disclosed.
  • The city of Pyeongtaek attempted three times to reach the 51st Fighter Wing via a telephone hotline to verify the reported leak, but the calls went unanswered, city officials told Yonhap. A city official said the hotline was a shared communication channel between the city and the U.S. air force unit.
  • Based on advice from firefighting authorities, and given the hazardous nature of white phosphorus, the city issued an evacuation advisory for residents. The advisory was lifted about 30 minutes later, after an on-site inspection found no immediate danger.
  • The U.S. military later issued a statement saying the leaked substance was not white phosphorus and contained no trace of the toxic substance, but was "non-hazardous surface corrosion resulting from environmental exposure over time."
  • White phosphorus, commonly used in smoke munitions, is an extremely toxic substance capable of burning human tissue down to the bone upon contact, according to the initial Yonhap report.
  • The U.S. military is investigating an interpreter for the U.S. military police, according to a claim reported by Yonhap in the second article, though details of the investigation were not provided.
