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.

Francis was urged in Belgium by both King Philippe and Prime Minister Alexander De Croo to do more to help abuse survivors in unusually forceful language for a papal foreign trip, always a carefully choreographed event.

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."
