Edinburgh Airport is returning to normal operation after a security alert prompted disruption for passengers, multiple outlets report. Authorities order an evacuation and set up a police cordon at the airport. Roads around the area are closed as police manage the incident, leading to delays and disruption for travellers during the period of heightened security. Police later state the event is not being treated as suspicious, indicating it is handled as a security incident without evidence of wrongdoing. As a result, services gradually resume and airport operations are expected to settle back into normal schedules. Travellers are advised to allow extra time and check for updates, with airports and transport staff continuing to manage the backlog caused by the temporary evacuation and restrictions. The reports consistently describe an initial security response involving evacuation and cordons, followed by reassurance from police that there is no indication the alert is suspicious, and a subsequent return to routine airport operations.
