Pope Francis said: “The statistics on the phenomenon of violence against children are shocking, but they also clearly show that the great majority of abuses are carried out in family or neighbourhood environments.
“The Catholic Church is perhaps the only public institution to have acted with transparency and responsibility.
“No-one else has done more. Yet the Church is the only one to have been attacked.”
He also praised his predecessor Pope Benedict for his work on the issue.
The UN’s report said the church had adopted policies and practices that had led to the continuation of abuse by the perpetrators.
It called for the Vatican to immediately remove all clergy who are known or suspected child abusers.
