1989
Satwant Singh (1962 – 6 January 1989) was one of the bodyguards, along with Beant Singh, who assassinated the Prime Minister of India, Indira Gandhi, at her New Delhi residence on 31 October 1984.
His attacks were in retaliation of Indira Gandhi's Operation Blue Star.
The motivation for the assassination of Indira Gandhi was revenge for the military operation carried out by the Indian government on Harmandir Sahib, in Amritsar, India.
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 submachine gun into her abdomen (thus, 33 bullets were fired in total, of which 30 bullets hit her).
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.
In his court statement, Satwant Singh appealed for end to communal violence in the country, while pinning the blame for the same on Indira and Rajiv Gandhi.
The execution was carried out on 6 January 1989.
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 house of the Parliament of India.
In the aftermath of the executions of Satwant Singh and Kehar Singh, communal violence occurred in Punjab, resulting in 14 Hindus being killed by militan and hundreds of Sikhs being killed across Delhi.
