The 'saint of the gutters' Mother Teresa was made a saint of the Roman Catholic Church by Pope Francis on Sunday. More than 100,000 pilgrims are expected to attend the ceremony which will be held shortly at the St. Peter's Square at the Vatican. 

Mother Teresa, the nun who worked in the slums of Kolkata to help the poor, will be honoured during the ceremony and will be canonised as a saint for performing miracles. Mother Teresa has been credited with performing two miracles after her demise, one of healing an Indian woman suffering from stomach cancer in 1998 and other of healing a Brazilian man, on his death bed, afflicted with brain cancer in 2008.
