By Jorge Otaola BUENOS AIRES (Reuters) -Argentines bid farewell to Pope Francis on Saturday, holding a massive open-air mass in front of the cathedral where he served as the archbishop of Buenos Aires before his papacy.

Although he never visited Argentina, Francis returned to South America when he visited Brazil in the first months of his papacy during his first overseas trip in July 2013. He visited four of the five nations that border Argentina – Brazil, Bolivia, Chile and Paraguay.
