BERLIN, GERMANY - SEPTEMBER 23: Iraqi Hussein Ibrahim (L) assists Iraqi Farah Alsammarraie (C) with bicycle repair at a temporary shelter for migrants constructed from shipping containers, on September 23, 2015 in the Koepenick district of Berlin, Germany. Almost half a million refugees, a number expected to increase, have crossed into Europe so far this year. After weeks of deliberations, the European Union decided upon a quota plan the previous day to distribute a share of them amongst EU member states in the largest instance of mass migrant movement on the Continent since World War II. Integration poses a particular challenge in Germany, where an earlier example of large-scale immigration by Gastarbeiters, or 'guest workers' brought over in a booming post-war economy, has been criticized for its failures in terms of incorporating foreigners, particularly Turks, into society.
