Pope Francis (C) walks around the Varginha favela in Rio de Janeiro, during a visit to the slum on July 25, 2013. The Varginha favela is a community of 1,000 people which for decades was under the sway of narco-traffickers until it came under police control less than a year ago. The first Latin American and Jesuit pontiff arrived in Brazil mainly for the huge five-day Catholic gathering World Youth Day. AFP PHOTO / TASSO MARCELO
