As many as 50 flights have been diverted from Dubai International Airport following the closure of both runways.
Operator Dubai Airports said the airport was closed at 06:45 resulted in the diversion of flights to a number of airports in the region including Dubai World Central, Al Ain, Doha Abu Dhabi, Dammam, Muscat and Bahrain among others.
The closures was caused by the loss of power to a critical runway backup system required during foggy conditions.
Runway operations were restored at 08:30.
“Dubai Airports is working with airlines, air traffic and ground services staff to restore operations, clear the backlog and limit customer inconvenience,” explained a statement.
As further flight delays are anticipated as a result of the disruption, passengers are advised to check with their airline or airline websites for further information on flight arrival and departure time.
