The motivation for the assassination of Indira Gandhi was revenge for the military attack carried out by the Indian government on Harmandir Sahib, in Amritsar, India. Harmandir Sahib was occupied by the Sikh militants Bhindranwale. The militants were flushed out and Bhindranwale was killed during the operation. The operation also caused damage to the temple premises and casualties on both sides which angered the Sikhs. Beant Singh drew a.38 revolver and fired three shots into Indira Gandhi's abdomen; as she fell to the ground, Satwant Singh fired all 30 rounds from his Sten automatic weapon into her abdomen. Both assassins subsequently dropped their weapons and surrendered. Beant Singh was shot to death during interrogation in custody soon after the assassination. Satwant Singh was arrested and later sentenced to death by hanging along with co-conspirator Kehar Singh. The sentence was carried out on 6 January 1989. During the Supreme Court trial, Satwant Singh, a former club wrestler from Amritsar, made the following statement "Let any part of my body, after my Shaheedi , removed and used by anyone who may need. However, if you need my eyes, let the authorities tell my parents. I have no hatred for any Hindu, Muslim, Christian, neither hatred for any religion. After my Shaheedi, let no Sikh throw any rock at any Hindu. I am not in favour of any retaliation or bloodshed over my Shaheedi. If we do create bloodshed, then there is no difference between us and Rajiv Gandhi. I am Proud of the task that I did! I do ardas in front of Waheguru! If I am blessed with a human life, then give me a death of the Brave when I am hanged. Forget one life, if I could I would give up a thousand lives to kill dushts like Indira Gandhi, and laugh as I become Shaheed by hanging…."
Aftermath
The assassination of Gandhi brought their immediate families into the limelight, resulting in their winning two Lok Sabha seats from state of Punjab. The Lok Sabha is a directly elected 543 member lower house of the Parliament of India. It was reported in the Indian press that during the aftermath of the executions of Satwant Singh and Kehar Singh, communal violence occurred in Punjab.
Honours
In 2003, a Bhog ceremony was held at the highest Sikh temporal seat in Akal Takht, located in the Golden Temple Complex in Amritsar, where tributes were paid to Indira Gandhi's assassins. In 2004, the anniversary of his death was again observed at Akal Takhat, Amritsar, where his mother was honored by the head priest and tributes were paid to Satwant Singh and Kehar Singh by various political parties. In 2007, the death anniversaries of Satwant Singh and his wife were observed in various parts of Punjab and other countries. On 6 January 2008, the Akal Takht declared Beant Singh and Satwant Singh "martyrs of Sikhism", while the SGPC also labeled them "martyrs of the Sikh nation". The Sikh-centric political party in India, Shiromani Akali Dal, observed the death anniversary of Beant Singh and Satwant Singh as "martyrdom" for the first time on 31 October 2008. Every 31 October since, this date has been observed at Sri Akal Takht Sahib. A film called Kaum de Heere was made about him in 2014.
