Pope Francis waves during a welcoming ceremony of the World Youth Day at Copacabana beach in Rio de Janeiro, Brazil on July 25, 2013. The first Latin American and Jesuit pontiff arrived in Brazil mainly for the huge five-day Catholic gathering World Youth Day. On the fourth day of his visit to Brazil and borne along by adoring crowds, Pope Francis waded into the country's ramshackle slums and onto the front line of its fierce national battle over poverty and corruption, before going to the much wealthier district of Copacabana for his welcome by the youth.
