Kerbala's international airport construction site was hit by an air strike, the management of the Imam Hussein shrine said in a statement. A civilian construction worker was killed.
The airport's construction is being funded by the shrine management.
The United States said it carried out the series of strikes on Thursday (March 12) against an Iran-backed militia in Iraq that it blamed for a rocket attack a day earlier which killed two American troops and a British soldier.
The Pentagon said the strikes targeted five weapons stores used by Kataib Hezbollah militants, including facilities housing arms used in past attacks on U.S.-led coalition troops.
Iraq's military condemned the air strikes, saying they had killed six people and describing them as a violation of sovereignty and a targeted aggression against the nation's formal armed forces.
