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

IDOMENI, GREECE - SEPTEMBER 02: People scramble up a steep track as they walk the final few kilometers towards the Macedonian border to have their papers processed before crossing on September 2, 2015 in Idomeni Greece. Several thousand migrant people are expected to arrive at the border today hoping to head North through Macedonia, after arriving in Athens in the previous few days. 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. (Footage by Dan Kitwood/Getty Images)
