TOPSHOTS Migrants sleep in the southern Serbian town of Presevo, near the border with Macedonia on July 16, 2015. The valley is their first stop after crossing into the Balkans nation, which is not an EU member but has land borders with four member states -- Bulgaria, Croatia, Hungary and Romania. The number of people apprehended crossing the Serbia-Hungary border alone has risen by more than 2,500 percent since 2010 -- from 2,370 to 60,602, according to a report by Amnesty International.
