YAYLADAG, Turkey — By road, the border was less than an hour’s walk from their villages, but 2,500 souls slowly crawled for two days in the broiling heat across the steep mountains. They feared for their lives all the way. The number of Syrian refugees has tripled since April, reaching 110,000 at camps in Turkey, Lebanon, Iraq and Jordan, according to the UN. The actual count is likely to be “significantly higher.” GlobalPost reports from the Turkish border.
