Mother Teresa, revered for her work with the poor in India, has been proclaimed a saint by Pope Francis in a ceremony at the Vatican.
Francis said St Teresa had defended the unborn, sick and abandoned, and had shamed world leaders for the “crimes of poverty they themselves created”.
Tens of thousands of pilgrims attended the canonisation in St Peter’s Square.
Two apparent cures of sick people after Mother Teresa’s death in 1997 have been attributed to her intercession.
In India, a special Mass was celebrated at the Missionaries of Charity, the order she founded in Kolkata (Calcutta).
