Ex-pope Benedict in rare public appearance at cardinals ceremony

Former pope Benedict XVI, who retired last year, made a rare public appearance on Saturday at a ceremony lead by his successor Pope Francis in St. Peter's Basilica to appoint new cardinals.

Benedict, who lives in a monastery inside the Vatican walls and had sworn to remain "hidden from the world", joined the cardinals in the front row of the basilica for the ceremony to create 19 new "princes of the Church."
