Turkey's Ambassador in Canberra has blasted as "unfair" international calls for his country to tighten its border with Syria to stem the flow of foreign jihadists, and said countries such as Australia should do more to stop such fighters leaving their own shores.

With Australia poised to begin delivering arms and munitions to Kurdish fighters in northern Iraq to help the battle against the ruthless Islamic State group (also known as ISIL), Ambassador Reha Keskintepe played down concerns that the weapons could fall into the hands of Kurdish terrorists the PKK, which has long been in conflict with Turkey.

While stressing that Turkey was "always concerned" about the danger of terrorists getting weapons, he said Ankara accepted the assurances given by the Kurdish regional government that it would keep a tight rein on the movement of the arms.

But Mr Keskintepe bristled at calls for Turkey to clamp down on its border with neighbouring Syria, the route of choice for foreign jihadists including Australians such as Khaled Sharrouf.
