Why the Syrian quagmire threatens Turkey

Turkey's tragic loss of at least 47 people in the car bombings in the border town of Reyhanli illustrates vividly that Turkey is not immune to the raging violence next door.

Turkey has suffered similar, though far less deadly events in the past year, including Syria downing a Turkish jet, the killing of five Turks in cross-border artillery fire and a car bomb blast at a Turkey-Syria border crossing in February killing more than a dozen people.
