How fighters are filtering across the Syrian-Turkish border
Turkey is handling tens of thousands of refugees trying to cross its border from Syria, but isn't sure how it will deal with the accompanying militants, their families and IS-affiliated fighters.
Some 60,000 people trying to escape Syrian and Russian attacks in the province of Aleppo are amassed at Turkey's border, and concerns are rising that there are militants among them.
According to information provided by the Turkish military and Kilis governorate, there are many foreign fighters among those trying to cross into Turkey. A well-placed security source at the border provided profiles of the refugees: civilians fleeing from the Aleppo-Azaz area, families of opposition fighters who used to live in the liberated areas, fighters supported by Turkey in the Bayirbucak and Aleppo-Azaz areas and foreign Islamic State (IS) militants.
Turkey, which had suspended its open-door policy, is now more flexible at the Hatay-Yayladag border area for those fleeing from the Bayirbucak region.
The Cilvegozu border crossing, the only official crossing between Idlib and Jisr al-Shughour, is only allowing the sick and wounded to enter Turkey.
