and-a-half-hour power cut at King Abdul Aziz International Airport South Terminal led to delays to six international and two domestic flights Sunday morning. Security staff prevented passengers from entering departure and arrival halls as inspection procedures were halted along with passport control and customs, causing a considerable backlog of passengers. Official sources said that all staff at airport were put on alert. “We stopped passengers entering due to the risks posed by a return to manual operations and the ease with which contraband materials could pass without inspection and reach the aircraft,” the sources said. “This led to a backlog in passengers at departure and arrival halls, and prevented monitoring persons boarding or arriving on international flights.” The outage occurred at 10 A.M. and delayed flights to London, Damascus, Amman, Doha, Kuwait and Casablanca, and flights to Madina and Riyadh.
