The 1984 anti-Sikh riots, also known as the 1984 Sikh massacre, were a series of organised pogroms against Sikhs in India following the assassination of Indira Gandhi by her Sikh bodyguards. Government estimates were that about 2,800 Sikhs were killed in Delhi and 3,350 nationwide, whilst other sources estimate the number of deaths at about 8,000–17,000.
