Catholics and others around the world await signs of smoke from the Vatican chimney as cardinals are now locked behind the heavy wood doors of the Sistine Chapel, sequestered from the world to elect a pope they hope can unite a diverse but divided global Church. Smoke from the first vote is expected after 7 p.m. ET (1700 GMT). White smoke will signal a new pope has been chosen. #Conclave #StPeterssquare #Vatican #VaticanCity #Pope #newPope #chimney #smoke #Catholic #Religion #live #Reuters #
