Four Iraqi soldiers were wounded last night in a rocket attack on their base north of Baghdad where American instructors were present until recently, Iraqi security officials said.
The Balad Air Base was attacked with at least six missiles and there were no casualties.
It came just days after Iran fired ballistic missiles at two bases in Iraq where US forces are stationed in retaliation for an American drone strike killing a top Iranian general.
There are currently no Americans at the Balad Air Base, located 80 kilometers north of Baghdad, and there were none during the attack, a coalition spokesman said.
The base previously housed American instructors, advisers and a group that provided maintenance services for F-16 jets, said an Iraqi military official who did not want to be named in compliance with regulations.
One Iraqi officer and three soldiers were wounded in the attack, Iraqi security officials said.
Some rockets hit a restaurant on the base, officials said.
No group claimed responsibility for the attack.
The recent rise in tensions between the US and Iran was fueled last month when a missile attack killed a US military contractor at a base in Iraq.
The US blamed a pro-Iranian paramilitary group for that attack and others.
US Secretary of State Mike Pompeo wrote yesterday, in a Twitter message, that he was "outraged" by the attack.
"Outraged by reports of yet another missile attack on an Iraqi airbase. Continued violations of Iraqi sovereignty by groups not loyal to the Iraqi government must stop," Pompeo said, and asked the Iraqi government to punish those responsible for the attack.
Official Iraqi military media confirmed that the attack had taken place but said that eight rockets hit the base and that two soldiers were wounded.
