Several rockets hit the Baghdad International Airport compound, near an adjacent US air base on Friday, causing no casualties, Iraqi police sources said.
A police source said an out-of-use Iraqi Airways plane was damaged in the attack.
Iraq's state news agency reported, citing the country's aviation authority, that there was no disruption to travel.
The US air base, known as Camp Victory, is located around the perimeter of Baghdad's civilian airport.
Rocket attacks have regularly struck the complex in recent years and are blamed by US and some Iraqi officials on Iran-aligned Shi'ite militia groups who oppose American military presence in the region.
On January 5, Katyusha rockets hit Iraqi military bases hosting US forces near Baghdad's international airport and west of the Iraqi capital.
A series of attacks this month, some of which the United States blames on Iran-aligned militia groups, have targeted bases or installations hosting US military and diplomatic personnel but have caused no US casualties.
Iranian political and military leaders have repeatedly demanded all US forces to leave Iraq and have vowed that their militia proxies will accomplish the goal. They have also promised revenge for the killing of Iranian general Qasem Soleimani who was killed in a US drone attack at the Baghdad airport in January 2020.
