"FILE - In this Oct. 30, 2007 file photo, people wave flags at the top of Corcovado mountain, in front of the statue, Christ the Redeemer, in Rio de Janeiro, after Brazil was officially chosen by FIFA as the host country for the 2014 World Cup. Brazil's foreign minister says ""all necessary measures"" are being taken to ensure security at next year's soccer World Cup and the 2016 Olympics following the deadly explosions at the Boston Marathon. While Brazil has never been a target of international terrorism, Monday's attacks underscore how vulnerable big sporting events can be. Rio will also host two major events later this year, the Confederations Cup soccer tournament and the World Youth Day, a Roman Catholic pilgrimage that's expected to be attended by Pope Francis and as many as 2.5 million visitors.
