No immediate claims of responsibility for an attack said by the Iraqi army caused no casualties.
Two rockets have headed a base at Iraqi airport in Baghdad, where they housed U.S.-led coalition troops in the second attack in ten days.
One of the projectiles was intercepted by the C-RAM rocket, artillery and mortar system deployed to protect U.S. forces in Iraq, a security source told AFP news agency. There were no immediate claims 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 these attacks on its troops and diplomats.
Tehran and Washington have had a presence in Iraq since 2003, with 2,500 U.S. troops still deployed.
Last week, three rockets crashed into the base area of Baghdad airport occupied by Iraqi troops and wounded one soldier.
Nearly 30 rocket or bomb attacks have targeted U.S. interests in Iraq, including Iraqi troops, the embassy or supply convoys to foreign forces, since U.S. President Joe Biden took over. possession of the office in January.
Two foreign contractors, an Iraqi contractor and eight Iraqi civilians have been killed in the raids.
Sometimes the operations are claimed by obscure groups that experts say are smokescreens for Iran-backed organizations that have long been present in Iraq.
“Occupying” American forces
The attacks come at a sensitive time, as Iran holds talks with world powers with the aim of returning the United States to a 2015 nuclear deal.
Baghdad reportedly organized a secret meeting of senior officials in Tehran and the US ally Saudi Arabia last month.
Iraq, nestled between its eastern neighbor Iran and Saudi Arabia in the south, has been working to become a mediator.
