SZEGED, HUNGARY - AUGUST 31: Hungarian police patrol the border from Serbia into Hungary close to the village of Roszke on August 31, 2015 near Szeged, Hungary. According to the Hungarian authorities a record number of migrants from many parts of the Middle East, Africa and Asia crossed the border from Serbia earlier this week, said to be due in part to the erection of a new fence that is due to be completed at the end of this month. 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 massive increase, said to be the largest migration of people since World War II, led Hungarian Prime Minister Victor Orban to order Hungary's army to build a steel and barbed wire security barrier along its entire border with Serbia, after more than 100,000 asylum seekers from a variety of countries and war zones entered the country so far this year.
