Indian Prime Minister Indira Gandhi was assassinated at 9:29 a.m. on 31 October 1984 at her residence in Safdarjung Road, New Delhi. She was killed by her bodyguardsSatwant Singh and Beant Singh in the aftermath of Operation Blue Star, the Indian Army's June 1984 assault on the Golden Temple in Amritsar which left the Sikh temple heavily damaged.
Operation Blue Star had a wide impact on politics in India as many Sikh youths joined the Khalistan movement. Indira Gandhi was unpopular among Sikhs due to her role in the operation, which had destroyed and damaged portions of the Akal Takht and caused massive casualties among Sikh pilgrims. Sikh sensibilities were offended at the alleged entry of army personnel with boots into the temple complex and the alleged destruction of Sikh scriptures and manuscripts in the temple library that caught fire due to explosives used during the operation. Such claims and other rumours led to an atmosphere of mistrust towards the government and ended in a conspiracy to assassinate Gandhi. This occurred within four months of the conclusion of the operation.
The perception of threat to Gandhi's life increased after the operation. Accordingly, Sikhs were removed from her personal bodyguard by the Intelligence Bureau due to the fear of assassination. However, Gandhi was of the opinion that this would reinforce her anti-Sikh image among the public and strengthen her political opponents. She ordered the Special Protection Group to reinstate her Sikh bodyguards, including Beant Singh who was reported to be her personal favorite.
At about 9:20 a.m. Indian Standard Time, on 31 October 1984, Gandhi was on her way to be interviewed by British actor Peter Ustinov who was filming a documentary for Irish television. She was walking through the garden of the Prime Minister's Residence at No. 1 Safdarjung Road in New Delhi towards the neighboring 1 Akbar Road office.
Gandhi passed a wicket gate guarded by Satwant and Beant Singh, and the two men opened fire. Beant fired three rounds into her abdomen from his .38 revolver, then Satwant fired 30 rounds from his Sten submachine gun after she had fallen to the ground. Both men then threw down their weapons and Beant said, "I have done what I had to do. You do what you want to do." In the next six minutes, Border Police officers Tarsem Singh Jamwal and Ram Saran captured and killed Beant, while Satwant was arrested by Gandhi's other bodyguards, along with an accomplice trying to escape; he was seriously wounded. Satwant Singh was hanged in 1989 with accomplice Kehar Singh.
Salma Sultan gave the first news of the assassination of Gandhi on Doordarshan's evening news on 31 October 1984, more than ten hours after she was killed. It is alleged[by whom?] that Gandhi's secretary R. K. Dhawan overruled intelligence and security officials who had ordered the removal of Sikh policemen as a security threat, including her assassins.
Beant was one of Gandhi's favorite guards, whom she had known for ten years. Satwant was 22 years old when he killed her, and had been assigned to Gandhi's guard just five months before her assassination.
Gandhi was taken to the All India Institutes of Medical Sciences in New Delhi at 9:30 a.m., where doctors operated on her. She was declared dead at 2:20 p.m. The postmortem examination was conducted by a team of doctors headed by Tirath Das Dogra, who stated that 30 bullets had struck Gandhi from a Sterling sub-machine gun and a revolver. The assailants had fired 33 bullets at her, of which 30 had hit; 23 had passed through her body, while seven remained inside. Dogra extracted bullets to establish the identity of the weapons and to correlate each weapon with the bullets recovered by ballistic examination. The bullets were matched with respective weapons at CFSL Delhi. Her body was taken in a gun carriage through Delhi roads on the morning of 1 November to Teen Murti Bhavan where her father stayed and where she lay in state. She was cremated on 3 November near Raj Ghat, a memorial to Mahatma Gandhi, at an area named Shakti Sthal. Her elder son and successor Rajiv Gandhi lit the pyre.
The Justice Thakkar Commission of Inquiry (headed by Justice Manharlal Pranlal Thakkar), set up to probe Gandhi's assassination, recommended a separate probe for the conspiracy angle behind the assassination. The Thakkar Report stated that the "needle of suspicion" pointed at R. K. Dhawan for complicity in the conspiracy.
Satwant Singh and alleged conspirator Kehar Singh were sentenced to death. Both were executed on 6 January 1989.
A Punjabi movie titled Kaum De Heere (People's Diamonds) highlighting the role/lives of the two guards that assassinated Indira Gandhi was set to be released on 22 August 2014, but was banned by the Indian government.
