American troops began withdrawing from northeast Syria ahead of a Turkish invasion that Kurdish fighters say will overturn the victory over the Islamic State of Iraq and the Levant (ISIL or ISIS) armed group. United States forces "will not support or be involved in the [Turkish] operation" and "will no longer be in the immediate area", White House Press Secretary Stephanie Grisham said in a statement. It was not clear whether that meant the United States would withdraw its 1,000 or so troops completely from northern Syria. Al Jazeera's Sinem Koseoglu reports from Istanbul.
