Dubai Airports said the closure of both runways at Dubai International at 6:45am 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 8:30am. Dubai Airports is working with airlines, air traffic and ground services staff to restore operations, clear the backlog and limit customer inconvenience,\" according to Dubai Airports. Further flight delays are expected as a result of the disruption. Dubai Airports advised passengers to check with their airline or airline websites for further information on flight arrival and departure time. From: Gulf News
