Air raid sirens shrieked briefly around Dubai airport Tuesday morning and passengers and staff directed to bomb shelters after UAE air defences warned of incoming missiles and drones fired by Iran. A video shot by a passenger showed people walking towards the shelters and also showed dozens of empty check-in counters, suggesting airline staff were also cleared. Data from flight tracking websites showed arrivals in a holding pattern near the cities of Fujairah and Al-Ain. Airport operations resumed about 30 minutes later. Sirens also sounded at the Bahrain airport.
