Roman Catholic cardinals have taken their first vote, and so far, a new Pope has not been selected.
Black smoke rose from the Sistine Chapel's chimney.
So far, the biggest issue for the papal conclave has been the weather.
Before the 115 cardinals trooped into the Sistine Chapel, thunder boomed and lightning flashed across the sky.
Then came a bout of hail, high winds and heavy rain.
The next round of voting begins early tomorrow morning our time.
