RIO DE JANIERO (CNN) -- Pope Francis is in Brazil this week for a special festival in Rio de Janeiro. It's his first foreign trip as pope.
While in town, the pope took time to bless the country's Olympic flags with holy water. Rio de Janeiro is the planned site for the 2016 summer Olympics.
The pope joins hundreds of thousands of pilgrims from around the globe who are in Rio for the 28th World Youth Day.
It's a weeklong festival held every two years and is aimed at revitalizing young Catholics, and the church around the world.
The pope announced this week that he plans to return to Brazil in 2017 to celebrate the 300th anniversary of the apparition of Our Lady of Aparecida to three fishermen.
