Just five kilometers separates Dursun Nahsen from her son Resad. But this short distance is the difference between her refuge in the relative peace of Turkey and the deadly battle for the town of Kobane.

And it is this wrenching separation, which begins at the barbed wire of the Turkish-Syrian border, that Dursun Nahsen is finding increasingly hard to bear.

The mainly Kurdish Syrian town of Kobane, where Resad is fighting alongside People's Protection Units fighters against Islamic State jihadists, is so close to the Turkish border that the fighting is clearly visible and audible on the other side.
