Pope Francis is to set up a Vatican committee to fight sexual abuse of children in the Catholic Church and offer help to victims. The announcement, by the archbishop of Boston, follows a meeting between the Pope and his eight cardinal advisers. It comes days after the Vatican refused a UN request for information on alleged abuse by priests, nuns or monks. Pope Francis has said dealing with sex abuse is vital for the Church's credibility. Earlier this week the Pope expressed his compassion for the many victims of sex abuse by priests around the world.
