BAPSKA, CROATIA - SEPTEMBER 25:  Migrants wait to cross into Croatia through the Serbian border on September 25, 2015 in Bapska, Croatia. More than 40,000 migrants have crossed into Croatia from Serbia since Tuesday last week. The Croatian government said on Wednesday it can not cope with this increasing number of migrants crossing its border and that Serbia should be also moving people on to Hungary and Romania. European Union ministers agreed on Tuesday to relocate 120,000 refugees among EU member states to ease the migration pressure on nations such as Greece and Italy.  (Photo by David Ramos/Getty Images)
