Migrants and refugees mainly from Syria and Iraq arrive in a beach near Skala Sikamineas village in Lesbos island, Greece on November 18, 2015. Lesbos and other Greek Aegean islands are at the forefront of the greatest migration challenge facing the European Union since World War II. Over 600,000 migrants and refugees, mostly from war-torn Syria, have landed in Greece this year, but nearly 500 have died in the Aegean.
