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.

VATICAN CITY (AP) — Cardinals failed again Thursday morning to find a successor to Pope Francis, sending black smoke billowing up through the Sistine Chapel chimney after two more inconclusive rounds of conclave voting.
