Pope Francis has recognised a second miracle attributed to Mother Teresa, clearing the way for the Roman Catholic nun to be declared a saint next year.
The miracle involved the healing of a Brazilian man with several brain tumours in 2008, the Vatican said.
Mother Teresa died in 1997 and was beatified - the first step towards sainthood - in 2003.
She won the Nobel Peace Prize for her work with the poor in the slums of the Indian city of Kolkata (Calcutta).
