Pope Francis is surrounded by children during his visit to the Sao Jeromino Emiliani church at the Varginha favela in Rio de Janeiro, 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 / YASUYOSHI CHIBA AFP PHOTO / YASUYOSHI CHIBA
