After a long wait, Mother Teresa was officially canonised by Pope Francis at the Vatican City on 4 September.
Over 1,20,000 people attended the ceremony at St Peter's Square to witness the canonisation.
Meanwhile, pilgrims also flocked to Mother Teresa's tomb in Calcutta, which has seen a sharp rise in the number of visitors since her beaitification.
As Mother Teresa became Saint Mother Teresa, political leaders joined social media users to pay homage to the Nobel Laureate. Here's a look at some of the tweets:

A number of users also criticised Mother Teresa, alleging that she did not deserve to be elevated to a saint.
For miracles I propose Nirmal Baba also to attain sainthood. He does that daily. 😂#FraudTeresa— Rita (@RitaG74) September 4, 2016
Let the trend #FraudTeresa be a lesson to all those non-Indian, non-Hindu fools who think they can come to our country and serve us.— Shirish Kunder (@ShirishKunder) September 4, 2016
The hashtag #FraudTeresa soon erupted into a battlefield, with many jumping in to defend the Nobel laureate.
Don't care if she deserves the Sainthood but all I know that she helped the poor and needy. That's a BIG DEAL for me. She ain't #FraudTeresa— Abba Dabba Jabba (@OB_noxious) September 4, 2016
