Migrants Gather At Greece-Macedonia Border As They Continue Their Journey Into Europe

IDOMENI, GREECE - SEPTEMBER 02: A Syrian migrant family walks to a border crossing that will lead them into Macedonia on September 2, 2015 in Idomeni, Greece. 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 Win McNamee/Getty Images)
