Approximately 2,000 people were evacuated from the terminal and moved onto the airport tarmac as authorities investigated the threat. Law enforcement personnel swarmed the facility as the evacuation procedures were implemented.

The FBI and local police agencies coordinated the response to what officials described as a threat situation at the airport. The nature of the specific threat was not immediately disclosed by authorities.

The evacuation affected normal airport operations as passengers and staff were relocated to secure areas outside the terminal building. Airport officials have not yet announced when normal operations will resume or provided details about flight delays or cancellations resulting from the incident.
