A violent incident occurred between the Sant Nirankari Mission and traditional Sikhs on 13 April 1978 at Amritsar, Punjab, India. Sixteen people—thirteen traditional Sikhs and three Nirankari followers—were killed in the ensuing violence. Clashes occurred when some Akhand Kirtani Jatha and Damdami Taksal members led by Fauja Singh protested against and tried to stop a convention of Sant Nirankari Mission followers. Fauja attempted to behead the Nirankari chief but was killed by his bodyguard. This incident is considered to be a starting point in the events leading to Operation Blue Star and the 1980s insurgency in Punjab.

During the same time Sanjay & Indira Gandhi decided to put their weight behind Bhindrawale. Their thirst for power made them to support that monster.
