No immediate claim of responsibility for an attack which, according to the Iraqi army, caused no casualties.
Two rockets targeted an Iraqi airport base in Baghdad housing US-led coalition troops in the second such attack in 10 days.
One of the projectiles was intercepted by the C-RAM counter-rocket, artillery and mortar system deployed to protect US forces in Iraq, a security source told AFP news agency. There was no immediate claim of responsibility for the attack.
Security officials said the rockets were launched from an area near the airport.
Washington routinely blames Iraqi factions linked to Iran for such attacks on its troops and diplomats.
Tehran and Washington have both been present in Iraq since 2003, with 2,500 American troops still deployed there.
Last week, three rockets crashed in the area of the base of Baghdad airport occupied by Iraqi troops, injuring a soldier.
Nearly 30 rocket and bomb attacks have targeted US interests in Iraq – including Iraqi troops, the embassy, or Iraqi supply convoys to foreign forces – since US President Joe Biden took office in January .
Two foreign contractors, an Iraqi contractor and eight Iraqi civilians were killed in the raids.
The operations are sometimes claimed by obscure groups, experts say, as smokescreens for Iranian-backed organizations long in Iraq.
American “ occupying ” forces
The attacks come at a sensitive time as Iran is engaged in talks with world powers aimed at bringing the United States back into a 2015 nuclear deal.
Last month, Baghdad reportedly hosted a secret meeting of senior Tehran officials and Saudi Arabia’s US ally.
Iraq, squeezed between its eastern neighbor Iran and Saudi Arabia to the south, is struggling to become a mediator.
