U.S. troops leaving Syria and heading to neighboring Iraq do not have permission to stay in the country, Iraq's military said Tuesday.
The statement appears to contradict U.S. Defense Secretary Mark Esper, who has said that under the current plan, all U.S. troops leaving Syria will go to western Iraq and the military would continue to conduct operations against the Islamic State group to prevent its resurgence in the region.
Speaking to reporters traveling with him to the Middle East, Esper did not rule out the idea that U.S. forces would conduct counterterrorism missions from Iraq into Syria. But he said those details will be worked out over time.
His comments were the first to specifically lay out where American troops will go as they leave Syria and what the counter-IS fight could look like. Esper said he has spoken to his Iraqi counterpart about the plan to shift the estimated 1,000 troops leaving Syria into western Iraq.
The statement by the Iraqi military, however, said that all American troops that withdrew from Syria have permission to enter northern Iraq's semi-autonomous Kurdish region, and then from there to be relocated out of Iraq.
"These forces do not have any approval to remain in Iraq," it said. The statement did not specify a time limit for how long the troops can stay there.
President Donald Trump ordered the bulk of U.S. troops in Syria to withdraw after Turkish President Recep Tayyip Erdogan made it clear in a phone call that his forces were about to invade Syria to push back Syrian Kurdish fighters whom Turkey considers terrorists.
The pullout largely abandons the Syrian Kurdish allies who have fought the Islamic State group alongside U.S. troops for several years. Between 200 and 300 U.S. troops will remain at the southern Syrian outpost of Al-Tanf.
Meanwhile, U.S. troops continued to pull out of northern Syria after Turkey's invasion into the border region. Reports of sporadic clashes have continued between Turkish-backed fighters and the U.S.-allied Syria Kurdish forces despite a five-day cease-fire agreement hammered out on Thursday between U.S. and Turkish leaders. The cease-fire expires Tuesday night.
Esper has said the troops going into Iraq will have two missions.
"One is to help defend Iraq and two is to perform a counter-ISIS mission as we sort through the next steps," he said, using an alternative acronym for the Islamic State group. "Things could change between now and whenever we complete the withdrawal, but that's the game plan right now."
The U.S. currently has more than 5,000 American forces in Iraq, under an agreement between the two countries. The U.S. pulled its troops out of Iraq in 2011 when combat operations there ended, but they went back in after IS began to take over large swaths of the country in 2014.
The number of American forces in Iraq has remained small due to political sensitivities in the country, after years of what some Iraqis consider U.S. occupation during the war that began in 2003.
