Migrants Cross Into Macedonia Before Continuing Their Journey

MACEDONIA - SEPTEMBER 04: Migrant families ride a train from Gevgelija to the Serbian border on September 4, 2015 in Macedonia. After stopping at a Serbian processing facility for migrants only, most people will continue on foot for the next 6 miles into the Serbian town of Preshevo. 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 Dan Kitwood/Getty Images)
