Migrants At The Serbian Border

HORGOS, SERBIA - SEPTEMBER 16: Migrant children stand behind a fence after Hungarian authorities closed their border on September 16, 2015 along the Horgos Border, near the town of Kanjiza. Thousands of migrants have funnelled their way across country to the small gap in the steel fence unopposed by the authorities. Since the beginning of 2015 the number of migrants using the so-called 'Balkans route' has exploded with migrants arriving in Greece from Turkey and then travelling on through Macedonia and Serbia before entering the EU via Hungary. The number of people leaving their homes in war torn countries such as Syria, marks the largest migration of people since World War II. (Photo by Srdjan Stevanovic/Getty Images)
