ALEXANDRA, SOUTH AFRICA - MAY 22: An unidentified man from Zimbabwe rests after being beaten on May 22, 2008 at Alexandra police station outside Johannesburg, South Africa. His shack was burned down during xenophobic attacks in the township a few days earlier. South Africa was rocked by xenophobic violence in May, where tens of thousands of African immigrants were chased out from poor townships and about sixty people were killed. Poor South Africans often have to compete with the ever-increasing African refugees arriving in the country. (Photo by: Per-Anders Pettersson/Getty Images).
