Caption:ALTERNATIVE CROP - BEST QUALITY AVAILABLE Alleged Islamic State (IS) militants stand next to an IS flag atop a hill in the Syrian town of Ain al-Arab, known as Kobane by the Kurds, as seen from the Turkish-Syrian border in the southeastern town of Suruc, Sanliurfa province, on October 6, 2014. Two flags of Islamic State (IS) jihadists seeking to take the Syrian town of Kobane were flying on the eastern side of the town, an AFP photographer reported. The flags, black with the Arabic lettering of the group, were seen by the photographer from the Turkish side of the border. One flew on a building while another larger flag was planted on a hill.
