Fighting escalates on the Syria- Turkey border in 2016 as U.S. Special Forces support Syrian rebels with the help of Turkish artillery to take border areas from Islamic State. Turkey was not willing to support Kurdish rebels in the fight against ISIS, leading to the shift to support Syrian rebels with the help of U.S. airstrikes. The result is a new flow of refugees to Turkey. The Turkish government created a zone on the Syrian side of the border for new refugees and called on the U.S. to create a safe zone.
