Thousands brave elements in St. Peter's Square

VATICAN CITY (WHDH) -- Thousands of people braved cold rain and packed St. Peter's Square Tuesday.

Onlookers eyes were fixed on the narrow chimney poking out of the Sistine Chapel roof.

Visitors were rewarded some three hours after the conclave began when thick black smoke billowed out of the chimney, signaling that no pope had been elected.
