The U.S.-led coalition fighting the Islamic State in Iraq and Syria has signed off on a “conditions-based” framework for the withdrawal of U.S. troops from Syria, the Pentagon announced Monday after national security adviser John Bolton said certain conditions must first be met before a pullout.

The U.S. is poised to support the coalition, Combined Joint Task Force–Operation Inherent Resolve, “while withdrawing troops in a strong, deliberate, and coordinated manner in order to ensure U.S. forces’ safety and protection,” according to a Pentagon spokesperson.
