People will be able to pay their respects to Francis through Friday. Given the large turnout of faithful wishing to pay homage to Pope Francis, the Vatican may extend the opening hours of St. Peter’s Basilica beyond the established time of midnight, the Vatican Press office said.

Thousands gathered in St. Peter's Square as Pope Francis' casket was brought for three days of viewing. The pontiff, who died Monday at age 88, will be celebrated this Saturday in an elaborate funeral mass.
