Pope Francis arrives at the John Paul II Diocesan Youth Center, in Sarajevo, Saturday, June 6, 2015. Pope Francis witnessed the horrors of Bosnia's fratricidal war of the 1990s and its slow process of healing Saturday during a one-day visit to Sarajevo, where he urged Muslims, Orthodox and Catholics to put the "barbarity" of the past behind them and work together for a peaceful future.
