More than 340 cars went up in flames Thursday as an uprising in the Swedish capital of Stockholm reached its fourth day. The rioters, mostly 20-somethings, threw rocks, broke windows, and destroyed cars as police lashed out, referring to them as “apes.” The violence stems from the police killing of a 69-year-old man carrying a machete—which was interpreted as a sign of rising police brutality. "We see a society that is becoming increasingly divided,” said Rami Al-khamisi, a man who works for social change in Sweden. Justice Minister Beatrice Ask spoke out Thursday to say she understands the anger. "Social exclusion is a very serious cause of many problems.”
