Firefighters worked for two hours to put out the small blaze, which began at around 1:15 pm and caused no injuries. Airport operators said 10 outbound international flights were delayed. They added later in an online statement that operations at the terminal were resuming.
The airport said the blaze broke out in the pump room for the airport's small aquarium, located in the arrivals concourse. "Terminal operations are now resuming, and Malta International Airport's recovery plan has been activated," it said in a statement in the late afternoon.
Hundreds of passengers were left standing outside the airport and some even on the apron. One flight to nearby Catania in Sicily was expected to take off 11 hours later than scheduled, according to the departures timetable. Flights to Stockholm, Cyprus, Krakow, London Gatwick and Dublin were also delayed. Flights from British airports Heathrow and Gatwick were diverted to Catania.
