Cardinals return to the Sistine Chapel on Thursday to resume voting for a new pope after the first conclave ballot failed to find a winner, sending billowing black smoke through the chapel chimney.
Some of the 133 voting cardinals had said they expected a short conclave to replace Pope Francis. But it will likely take a few rounds of voting for one man to secure the two-thirds majority, or 89 ballots, necessary to become the 267th pope.
