An African migrant laborer runs near a heap of garbage outside the camp known as the “Great Ghetto” near Foggia, Italy on August 8, 2018. The camp was bulldozed by the authorities following a fire that killed three migrants. But with accommodation at a premium, the ghetto has risen again from the rubble - a shanty town of tiny shacks made of corrugated iron and wooden planks. Home to up to 1,000 people, it has zero amenities. Other migrants live in an official, albeit overcrowded and decrepit refuge, which has running water and electricity. It was set up last year after the Great Ghetto was bulldozed. (Photo by Alessandro Bianchi/Reuters)
