Homeless people had VIP seats at a special Mass on Sunday in St Peter's Basilica, where Pope Francis lamented attitudes that cut off many of the world's poor from the benefits of progress.

Francis had invited homeless and impoverished people to one of his last Masses during the Holy Year of Mercy he established to stress that virtue. The Holy Year ends on November 20.

Along with cardinals and other prelates, homeless people sat near the ornate central altar.

In his homily, Francis said God and our neighbour are the most valuable riches in life.
