A long crisis

Many of the millions of people fleeing wars in Syria, Iraq, and Afghanistan are traveling through the Balkans in the hope of reaching Western Europe. European countries have received many thousands of applications for asylum, with Germany receiving more than a half a million since 2011, according to the New York Times. European leaders are divided over how the region should handle the influx.

Hungary is building a fence on its border with Serbia in order to block the entry of more migrants into the country. German Chancellor Angela Merkel has said that offering protection to the migrants is a task all of Europe should share. And countries such as Greece—still struggling with its own economic troubles—are straining to accommodate the newcomers.
