Throngs of mourners are lining St. Peter's Basilica in the Vatican to pay their final respects to Pope Francis, whose body is lying in state.

Vatican authorities kept St. Peter's Basilica open all night as an estimated 50,000 people lined around St. Peter's Square and out of the Vatican into Rome to view the body of Pope Francis lying in state.

The sounds of bells and prayerful chants echoed throughout Vatican City as Francis’ body was carried in a simple wooden coffin through the square.
