Vienna temple attack

On Sunday 24–25 May 2009, several people in the Guru Ravidass Gurdwara in Vienna, Austria, were attacked by six men carrying knives and guns. Two of the victims were identified as visiting Dera Sach Khand head Niranjan Dass, 68, and another leader, Ramanand Dass, 57, who suffered multiple gunshot wounds and died the next day in hospital. At least 15 others were injured, including 4 of the attackers, who were in the end subdued by the other worshipers. This shooting came to be known as the Vienna attack. It was described as a terrorist attack committed by Sikh fundamentalists, who viewed the dera as "blasphemous" and adhering to the Sikh maryada. The incident sparked riots across Northern India. It led to the formalization of a separate Ravidassia religion from mainstream Sikhism.
