MUNICH, GERMANY - AUGUST 29:  A policeman distributes cups of water to migrants in a holding area who had arrived by train at Munich Hauptbahnhof main railway station and were detained by police because they had no passports on August 29, 2015 in Munich, Germany. According to police hundreds of migrants are arriving in southern Germany daily, either via people smugglers from Hungary along the A3 highway or via trains coming from Italy. Germany is expecting to receive 800,000 asylum-seeking migrants this year and is struggling to cope with the record number.  (Photo by Sean Gallup/Getty Images)
