Pope Francis' one-day visit to the French island of Corsica on Sunday, two days before his 88th birthday, puts a dual focus on the Mediterranean, highlighting local traditions of popular piety on the one hand and migrant deaths and wars on the other.

A brass band and children in traditional garb greeted Francis at the airport, and thousands lined the route of his motorcade waving flags and shouting greetings. The pope stopped along the way to listen to a choir of children singing.
