KOS, GREECE - AUGUST 31: A migrant man from Pakistan relaxes with a cigarette on board the Blue Star ferry bound for Athens from Kos on August 31, 2015, Greece. Migrants from many parts of the Middle East and African nations continue to flood into Europe before heading from Athens, north to the Macedonian border. 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) less
