A convoy of peshmerga vehicles is escorted by Turkish Kurds on their way to the Turkish-Syrian border, in Kiziltepe near the southeastern city of Mardin October 29, 2014. Iraqi peshmerga fighters arrived in southeastern Turkey on Wednesday en route for the Syrian town of Kobani to try to help fellow Kurds break an Islamic State siege which has defied U.S.-led air strikes. Kobani, nestled on the border with Turkey, has been under assault from Islamic State militants for more than a month and its fate has become a key test of the U.S.-led coalition’s ability to combat the Sunni insurgents.
