"Never again war," Pope Leo XIV echoed his predecessor, the late Pope Francis, in the newly-chosen pontiff's first Regina Coeli prayer in St Peter's Square in front of the faithful on Sunday.
An estimated 150,000 people were in the square, and heavy security measures had been in place since the morning. The pontiff emerged from the central Loggia of the Basilica with a "Good Sunday" and then began the prayer amidst the crowd's applause.
