Pope declares Mother Teresa a saint

Pope Francis has declared Mother Teresa of Calcutta, known as the "saint of the gutters" during her life, a saint, just 19 years after her death.Applause erupted in St Peter's Square at the Vatican even before Francis finished pronouncing the rite of canonisation at the start of the Mass for the nun on Sunday, with the attendance of tens of thousands of pilgrims.

Pilgrims streamed into the square from early morning ahead of a service to honour the nun and Nobel peace laureate, who worked among the world's poorest in the slums of the Indian city now known as Kolkata.

"For the honour of the Blessed Trinity ... we declare and define Blessed Teresa of Calcutta (Kolkata) to be a Saint and we enroll her among the Saints, decreeing that she is to be venerated as such by the whole Church," the pontiff said in Latin.
