Hundreds of thousands gathered in St. Peter's Square on Sunday, a day after Pope Francis' funeral, for another ceremony to honour him on the second of nine official days of mourning for the global Catholic Church.

Guests at the Vatican service were told of the Pope's call to "build bridges", as Trump and Zelensky were pictured meeting inside St Peter's Basilica.
