PARIS — The migrant crisis in France has shifted from the “Jungle” of Calais to the streets of Paris, with hundreds camped out in tents in the city’s northern neighborhoods and dozens more arriving each day.

The wildcat encampments have thrust the European migrant issue in the face of Parisians and once again underscored the French government’s inability to resolve a problem it hoped Italy and Germany would forestall.

The numbers have been far greater in those countries, but migrants — largely Africans and Afghans — nonetheless keep trickling into Paris. As many as 100 migrants are arriving a day, according to aid groups. Most have vague hopes of reaching Britain or getting asylum in France.

Stretching far up the Avenue de Flandre in the city’s working-class 19th Arrondissement and bunched under nearby subway overpasses at the Jaurès and Stalingrad Métro stations, the enclaves of pup tents are islands of misery in the midst of first-world prosperity.
