BUDAPEST, HUNGARY - SEPTEMBER 14: Migrants make their way to board a train leaving for the Austrian border at the Keleti railway station on September 14, 2015 in Budapest, Hungary. Migrants who arrive in Budapest overnight gather in the morning at the railway station as they try to be on the early trains leaving Budapest due to fears that the borders will possibly close in the coming 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. (Photo by Jeff J Mitchell/Getty Images)
