Pope Francis urges action to stop abuse in Catholic church

Pope Francis has called for concrete action to address the sexual abuse scourge plaguing the Catholic Church as a four day summit in Rome kicks off. Nearly 200 priests, bishops and other Catholic church delegates are in Rome for the summit. Victims of sexual abuse will be able to speak of their experiences - though they won't address the meeting in a formal capacity.
