THE JUNGLE MIGRANT CAMP, CALAIS, HAUTS-DE-FRANCE, FRANCE - 2016/10/27: Refugees and migrants stand in line waiting to leave the Calais Jungle. The Jungle was an illegal migrant camp in the northern French town of Calais. The camp attracted migrants and refugees from across the Middle East, North Africa and Sub-Saharan Africa who planned to illegally enter the UK. Eventually the French authorities were forced to close the Jungle because it had grown out of control and was becoming both a public health risk and a hub of criminal activity. The Calais Jungle was closed in October 2016. (Photo by Edward Crawford/SOPA Images/LightRocket via Getty Images)
