Turkey sees its deal with the U.S. to carve out a narrow security zone in northern Syria as just the beginning, two Turkish officials said, with Ankara determined to purge Kurdish fighters from a much larger section of the border region.
After weeks of difficult negotiations, the NATO allies agreed this month to jointly patrol an area stretching 125 kilometers (78 miles) between the Syrian towns of Tal Abyad and Ras al-Ayn, and up to 15 kilometers deep, according to the officials, who have direct knowledge of the talks but asked not to be identified in line with regulations barring them from talking to the media.
