The British Airways Airbus A319, flight #767, came from London Heathrow to Oslo with around 100 passengers.
Hans Holmgrunn of the Gardermoen police station told local newspaper Eidsvoll Ullensaker Blad that around 20 of the passengers were ill with nausea, diarrhea and vomiting.
Jo Kobro of Oslo Lufthavn Gardermoen said that a public health official was heading for the airport to go on board the fight and evaluate the situation.
In the meantime, all passengers were held on board.
Holmgrunn indicated that many of the passengers had come from Burma and had landed in both Thailand and England on their way to Oslo.
