The U.S. military informed its counterparts in Baghdad on Monday it was preparing for "movement out of Iraq," a day after Iraqi parliament urged the government to oust foreign troops.
The head of the U.S. military's Task Force Iraq, Brig. Gen. William Seely, sent a letter to the head of Iraq's joint operations command, a copy of which was seen by AFP.
The letter said troops would "be repositioning forces over the course of the coming days and weeks to prepare for onward movement."
A U.S. defense official and an Iraqi defense official confirmed the letter was real and had been delivered.
