The bells of St. Peter’s Basilica tolled to mark the end of the funeral of Pope Francis in Vatican City, where throngs of mourners had gathered to give a final send-off to a pontiff who was celebrated during the service as a champion of migrants and the poor.

Pope Francis, who reigned for 12 years, was laid to rest Saturday at the St. Mary Major Basilica in Rome. He is the first pope to be buried outside the Vatican in over a century.

World leaders and rank-and-file Catholic faithful bade farewell to Pope Francis in a funeral Saturday that highlighted his concern for people on the peripheries and reflected his wish to be remembered as a simple pastor.
