The exercise, scheduled to begin at 9am, will simulate an emergency situation in order to enhance safety standards and ensure staff are fully prepared to respond to potential incidents.
Airport officials stressed that the drill is a training exercise only and not a real-world event.
Travellers and service users are requested to refrain from taking photos or videos during the drill to avoid any misunderstandings.
“We apologise for any inconvenience caused and thank all passengers and airport users for their cooperation,” the announcement said.
