KILIS, Turkey (Reuters) - Turkish shopkeeper Mehmet Baykal knew he had less than 10 seconds to dive under his desk when he heard another rocket being fired from Islamic State-held territory across the border in Syria.

Once a safe haven for tens of thousands of Syrian refugees, this tiny Turkish border town has now become a frontline in its war. So frequent is the rocket fire across what is in effect also NATO's front line that residents know instinctively how long they have to take cover.
