TOPSHOT - A woman carries a child as she walks with other migrants after crossing the Macedonian border into Serbia, near the village of Miratovac, on January 29, 2016. More than one million people reached Europe's shores in 2015 -- the majority of them refugees fleeing conflict and persecution in Syria, Afghanistan and Iraq -- in the continent's worst migration crisis since World War II. The International Organization for Migration estimates that some 31,000 migrants have reached Greece by sea so far this year, hoping to start new lives in Germany, Sweden and elsewhere in the European Union.
