Former Pope Benedict made a surprise entrance into St. Peter's Basilica to attend a ceremony at which his successor, Pope Francis, was elevating 19 prelates to the high rank of cardinal.
Benedict, who resigned a year ago, sat quietly wearing a long white overcoat in the front row along with other cardinals.
It was the first time he has attended a papal ceremony since his resignation, although he and Francis have met several times.
