Pope Francis on Sunday wrapped up a weekend trip to Belgium, where he faced some of the strongest criticism yet levied during one of his foreign trips. The 87-year-old pontiff was pressed by high-profile figures at three of the five major events on his three-day visit in unusual and sometimes fierce language for a papal trip.

Speaking to a crowd of around 39,000 in the King Baudouin Stadium in Brussels, the pontiff wrapped up a difficult visit to Belgium by saying, "There is no place for the covering up of abuse."

On Saturday, Pope Francis acknowledged that the abuse scandal had created "atrocious suffering and wounds," and undermined the faith.
