Migrants Brave River in Search for New Route to Europe

Migrants march on a road, north of Idomeni, Greece, during an attempt to reach Macedonia on a route that would bypass the border fence on March 14, 2016. Hundreds of migrants and refugees walked out of an overcrowded camp on the Greek-Macedonian border Monday, determined to use a dangerous crossing to head north.

The closure, following the lead taken by neighboring countries, has effectively sealed the so-called western Balkan route, the main migration route that has been used by hundreds of thousands of migrants to reach countries in western Europe such as Germany.
