Riot police walk in front of a burning barricade made by protestors in Rio de Janeiro's sister city, Niteroi, Brazil, Wednesday evening, June 19, 2013. Rio de Janeiro and Sao Paulo city leaders said Wednesday that they reversed an increase in bus and subway fares that ignited anti-government protests. Many people doubted the move would quiet the demonstrations which have moved well beyond outrage over the fare hikes into communal cries against poor public services in Latin America's biggest nation.
