US blames Iran-backed militia for attack on air base in Iraq

Washington - The United States accused an Iranian-backed militia of carrying out a rocket attack on a U.S. air base in Iraq that injured seven people, two of whom had to be evacuated for additional medical treatment.

'We're sure that it was an Iranian-backed Shia militia group,' U.S. Defense Secretary Lloyd Austin told reporters Tuesday during a news conference in Annapolis, Maryland, with Australian officials.
