Pope Francis visits the King and Queen of Belgium, in Laeken Castle. The Holy Father then met with University teachers in Leuven. Pope Francis said that the Catholic Church must "seek forgiveness" for the "scourge" of child sex abuse, where in Belgium the clergy's dark past looms large. In a speech beginning his three-day visit, Francis denounced the "tragic instances of child abuse" as a stain on the Church's legacy. IMAGES
