Iraq condemned overnight U.S. air strikes on Friday, with its military saying six people were killed.
Iraq described them as a violation of sovereignty and a targeted aggression against the nation’s regular armed forces.
President Barham Salih said repeated such violations could cause Iraq to unravel into a failed state and revive the Islamic State militant group.
The military warned the air strikes would have consequences while the foreign ministry said it summoned the U.S. and British ambassadors.
The United States said it carried out the series of strikes on Thursday against an Iranian-backed militia in Iraq that it blamed for a rocket attack a day earlier which killed two American soldiers and a British soldier.
U.S. says threat from Iran still high after U.S. retaliatory strikes in Iraq.
Long-standing antagonism between the U.S. and Iran has mostly played out on Iraqi soil in recent months.
Iraq’s Joint Operations Command said in a statement that the reason the U.S. gave for the attack was an excuse.
“The pretext that this attack came as a response to the aggression that targeted the Taji base is a false pretext; one that leads to escalation and does not provide a solution.’’
It said that as well as the six killed, 12 people had been wounded in the U.S. air strikes, and that infrastructure, weapons and equipment at targeted military sites were destroyed.
The Pentagon said the strikes targetted five weapons stores used by Kataib Hezbollah militia, including facilities housing arms used in past attacks on U.S.-led coalition troops.
Official Iraqi casualty figures showed no paramilitary fighters had been killed.
The military said three soldiers, two policemen and one civilian were killed, according to an initial toll, and that four soldiers, two policemen, a civilian, and five militiamen were injured.
Iraqi religious authorities said the civilians killed and wounded were construction workers at an airport building site in the Shi’ite Muslim holy city of Kerbala.
