The fire broke out in the two-floor departure hall called "Nineveh" and did not result in human losses.
The Airport's administration said the material damage is slight.
Outgoing flights were not affected, and an investigative committee has been formed to determine the cause of the fire.
Earlier on Tuesday, firefighters at Baghdad's international airport on Tuesday put out a fire that broke out in its departure hall that temporarily suspended flights.
