Key summit in Vatican concludes with Pope calls for 'all-out battle' to curb abuse

Pope Francis, ending a landmark Vatican conference on clergy sexual abuse of minors, called on Sunday for an "all-out battle" against a crime he called abominably and that should be "erased from the face of the earth".

Francis vowed that the Roman Catholic Church would "spare no effort" to bring abusers to justice and will not cover up or underestimate abuse. He promised that guidelines used by national bishops conferences to prevent abuse and punish perpetrators will be reviewed and strengthened.
