There was a U.S. airstrike southwest of Baghdad today, a new area of operations for U.S. fighter aircraft, ABC News reported.
But this isn't an indicator of expanded airstrikes in Iraq, a U.S. official told ABC News.
A request was received from the Iraqis to provide air support for an Iraqi unit that was engaged in a firefight with fighters with the Islamic militant group ISIS, the official said.
An aircraft was re-directed and conducted a strike to support the Iraqi ground troops, the official said.
The U.S. Central Command, or CentComm, is expected to detail the attack later today.
