The U.S. military is set to end its decades-long presence, with remaining troops in northern Iraq withdrawing by the agreed deadline.
The Iraqi government has linked this withdrawal to the disarmament of militias, but many groups show no signs of complying.
Tehran-backed militias have attacked U.S.-linked targets since February, and the ongoing conflict with Iran complicates the situation.
The withdrawal has raised concerns in the Kurdish region about increased vulnerability.
Meanwhile, negotiations continue over the integration of militias into the Iraqi military structure.
