But Esper said Sunday that many of the U.S. troops leaving Syria will be relocated to Iraq.

"One is to help defend Iraq and two is to perform a counter-ISIS mission as we sort through the next steps," he said, adding that the troop withdrawal would take "weeks not days."

"Things could change between now and whenever we complete the withdrawal, but that’s the game plan right now," Esper said.

The Defense chief did not rule out the possibility of U.S. forces conducting counterterrorism missions from Iraq into Syria. He also reportedly said that he'd spoken with his Iraqi counterparts about the move, which will place more than 700 U.S. troops in western Iraq. More than 5,000 American troops are currently stationed in Iraq as part of an agreement between the two nations, the AP reported.

The forces deployed in northern Syria had been assisting the Kurdish YPG, which leads the Syrian Democratic Forces.

Turkey considers the Kurdish-led forces, which have proved to be the U.S.'s most effective allies in its fight against ISIS, to be a terrorist insurgency.

Reports surfaced last week that hundreds of ISIS supporters escaped from a Kurdish-established detention facility following a Turkish airstrike.

Vice President Pence announced last Thursday that the United States and Turkey reached a deal to temporarily suspend Ankara's incursion. However, the AP noted that sporadic clashes have continued despite the five-day cease-fire.

Esper acknowledged those reports but said that the cease-fire "generally seems to be holding."
