No winner in first vote to elect new pope

 Rome (CNN) -- Black smoke billowed from the chimney of the Sistine Chapel Tuesday night, indicating that cardinals gathered at the Vatican to elect a new pope had not chosen one in the first ballot of their conclave.

The start of the secret election got underway earlier in the day, as the heavy wooden doors to the chapel swung closed on the 115 Roman Catholic cardinals charged with selecting the next pontiff.

The next round of voting will begin Wednesday morning. Results will be revealed by puffs of smoke from the chimney following each ballot.

Black smoke, no pope. White smoke, success.
