The cardinals, who broke for lunch and will reconvene this afternoon, are expected to continue casting ballots at the Vatican until one among them receives at least two-thirds of the vote. The release of white smoke, or fumata bianca in Italian, will signify that they've elected a pope, as will the ringing of the bells of St. Peter's Basilica.

Officials of the Catholic Church are gathering to select Pope Francis' successor during the papal conclave. Watch here for the black or white smoke.
