ROME (REUTERS) - Rome's main airport was closed on Thursday after a fire broke out in a baggage storage area but there were no serious injuries, officials said.

The airport would remain closed until 2 pm (8pm Singapore time), they said.

The fire broke out shortly after midnight in an underground baggage area of Fiumicino airport's Terminal 3, which is used for international flights.

At least three people suffered smoke inhalation, a fire brigade official said.

He said the fire was under control and that the cause of the fire was unknown.

Nearly 20 fire fighting trucks were at the airport. The main highway linking it to Rome was closed to allow emergency vehicles to pass.
