A suspect device found in a toilet on board Flight AF463 from Mauritius to Paris was a false alarm.

The plane was diverted to Kenya and made an emergency landing at Mombasa's Moi International Airport.

The CEO of Air France, Frederic Gagey, said the object, which was made up of cardboard, pieces of paper and a timer, was not capable of causing an explosion.

Kenyan authorities said an undisclosed number of passengers who were on the flight were being questioned.

The Boeing 777 aircraft, which was en route to Paris was safely evacuated after it landed at 12.37am (9.37pm Saturday Irish time).

There were 459 passengers and 14 crew on board.

Earlier, the airline said all passengers were evacuated from the aircraft by its emergency slides.

Kenya Civil Aviation Authority said on its Twitter account that flights from Mombasa airport were disrupted due to the emergency landing, but normal operations resumed a few hours later.
