US, Turkey aim for IS-free zone in northern Syria

The move is expected to further embroil Turkey in Syria's civil war and set up a potential conflict with U.S.-backed Kurdish forces.

A U.S. official said the creation of an "Islamic State-free zone" would ensure greater security and stability in the Turkish-Syrian border region. However, the official said any joint military efforts with Turkey would not include the imposition of a no-fly zone.
