Faithful react in St Peter's Square after black smoke billowed from the chimney of the Sistine Chapel announcing that Catholic Church cardinals failed to elect a new pope during a conclave on March 13, 2013 at the Vatican. The 115 cardinals held a first inconclusive vote in the Sistine Chapel yesterday as they began the process of finding a successor to Benedict XVI, who brought a troubled eight-year papacy to an abrupt end by resigning last month.
