Italian Cardinal Pietro Parolin and Filipino Cardinal Luis Tagle are considered top contenders, according to The Associated Press. Parolin, who served as Pope Francis' Secretary of State, is well-known among the cardinals. Tagle, head of the Vatican's evangelization office, is often mentioned as a potential first Asian pope.

Visitors have been barred from the Sistine Chapel, where the conclave of cardinals will vote to elect the next pope.
