President Dilma Rousseff, who has been largely absent from the public eye throughout the crisis, called off a trip to Japan and gathered her chief ministers to deal with the unrest. Brazilian media cited official figures when reporting that more than a million people demonstrated yesterday. In Rio de Janeiro, where an estimated 300,000 protesters poured into the central area, riot police clashed with clusters of mostly young men who had T-shirts wrapped around their faces. Peaceful protesters were caught up in the fray as police fired tear gas into the crowd and at times used pepper spray. At least 40 people were injured.
