On Easter Sunday, Pope Francis presided over Easter vigil Mass in St. Peter's Basilica, surrounded by a colorful array of spring flowers that had been delivered to the Vatican square the day before. The pope opened the celebration of Mass in St. Peter's Square, joined by dozens of prelates and tens of thousands of pilgrims and tourists. The pope is recuperating from bronchitis, but is expected to deliver a speech about conflicts in the world at the end of Holy Week.
