Pope Francis delivers his message during the Angelus noon prayer he delivered from the window of his studio overlooking St. Peter's Square, on he occasion of All Saints Day , at the Vatican, Friday, Nov. 1, 2013. The Pontiff has led tens of thousands of people in silent prayer in memory of African migrants who died of thirst after being stranded in the Sahara. Faithful in a packed St. Peter's Square Friday bowed their head as the pope asked for prayers for "our brothers and sisters" who perished "from thirst, hunger and exhaustion" in the journey to try to reach a better life.
