FILE - In this Sept. 28, 2014 file photo, Syrians are seen at the Turkish border crossing of Oncunipar, Kilis, Turkey. The Turkish border crossing of Oncunipar, an hour’s drive from the embattled Syrian town of Aleppo, is a chaotic buzz of people waiting to pass into one of the most violent regions in the world. Border guards stand by with machine guns to prevent Islamic militants from joining the flow, but within their sight smugglers offer to take travelers across for a surprisingly small fee.
