Authorities in Benina Airport said water flooded the passenger terminal and parts of the car park, prompting the decision to halt flights.
The vice president of the airport, Osama Alfargany, said “the water came all the way into the passenger halls, which was approximately one to one and a half metres high,” according to Reuters news agency.
The airport ”took the necessary procedures and halted all flights temporarily as well as taking all safety and security measures including disconnecting the airport’s power supply,” he added.
