A flight attendant for the Mideast long-haul carrier Emirates has been hospitalized in Uganda after falling out of an open emergency door on a Boeing 777 that was parked on the tarmac.

Civil aviation authorities in Uganda say the incident happened on Wednesday at the Entebbe International Airport.

They issued a statement saying the female flight attendant "unfortunately fell off" of the plane.

An investigation is underway.

Emirates said in a statement on Thursday that the flight attendant "unfortunately fell off from an open door while preparing the aircraft for boarding on flight EK730 from Entebbe."

The airline added: "We are providing all possible support and care for the affected crew, and will extend our full co-operation to the authorities in their investigation."
