France - Immigration - Immigrants and refugees in Calais

Migrants walk along the railway track leading to the EuroTunnel at night, in Calais, France, August 10, 2015. Migrants are attempting to enter the United Kingdom illegally by stowing away on lorries, ferries, cars, or trains travelling through the Port of Calais or the Eurotunnel Calais Terminal. The migrants are a mix of refugees, asylum seekers and economic migrants from Darfur, Afghanistan, Syria, Iraq, Eritrea and other troubled areas of the world.
