Three Katyusha rockets fell on Baghdad International Airport, the military-run Security Media Cell said in a statement early on Friday.
The rockets landed near the air cargo terminal, burning two vehicles and injuring several people, Security Media Cell said.
At least one person was killed and 9 others wounded, police and medical sources said.
There was no immediate claim of responsibility.
