SANLIURFA, TURKEY -  SEPTEMBER 27: (TURKEY OUT) A Turkish soldier guards on the Syrian borderline in the southeastern town of Suruc on September 27, 2014 in Sanliurfa province of Turkey. Nearly 140,000 Syrian Kurds have fled into Turkey since last week, the fastest exodus of the entire three-year civil war. The United Nations refugee agency said on Tuesday it was making contingency plans in case all 400,000 inhabitants of the Syrian Kurdish town of Kobani fled into Turkey to escape advancing Islamic State militants.
