Turkey is increasingly concerned about the proliferation of Al Qaeda-linked fighters along its border with Syria. This week its military fired on jihadist targets in Syria.
Turkey was an early supporter of Syria's rebellion, keeping its border open for refugees and aid, but has became wary of jihadi groups operating on its turf.
Turkey is openly opposed to the Assad regime and has supported rebel groups, allowing weapons to cross the Turkish border to Assad's chagrin.
The unrest is unlikely to become a “Turkish Spring,” but it is testing democracy in Turkey.
Prime Minister Erdogan temporarily placated Turkish protesters by pausing development of Gezi Park, but their grievances run deeper. It will take more to stop demonstrations for good.
