Dubai Airports confirms the closure of both runways at Dubai International this morning at 0645 resulted in the diversion of 50 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 were caused by the loss of power to a critical runway backup system required during foggy conditions. Runway operations were restored at 0830. Dubai Airports is working with airlines, air traffic control and ground services staff to restore operations, clear the backlog and limit customer inconvenience. As further flight delays are anticipated as a result of the disruption, passengers are advised to check with their airlines or airlines websites for further information on flight arrivals and departure times
