All U.S. forces involved in the anti-ISIS fight will withdraw from northeast Syria in the coming days, according to two U.S. officials close to the conflict. Only a small garrison of U.S. troops will remain at al-Tanf near Syria's border with Iraq and Jordan.
The troops in border areas are endangered by Turkey's incursion against Kurdish-led forces. The move is a sudden change in policy by the Trump administration.
