A demonstrator walks on a main highway while blocking traffic to protest alleged abuses of power by governor Sergio Cabral in Rio de Janeiro, Brazil, Friday, Aug. 15, 2013. Cabral has been the target of protests since June, when a wave of mass demonstrations against government corruption, unresolved missing persons cases and poor public services swept Brazil. Protesters allege Cabral is corrupt and want an investigation into spending on projects linked to next year's World Cup and the 2016 Olympics, which Brazil is hosting.
