The 1984 anti-Sikh riots or the 1984 Sikh Massacre or the 1984 genocide of Sikhs was a series of pogroms directed against Sikhs in India, by anti-Sikh mobs, most notably by members of the Congress party, in response to the assassination of Indira Gandhi by her Sikh bodyguards. There were about 2800 deaths all over India, including 2100 in Delhi.The Central Bureau of Investigation, the main Indian investigating agency, is of the opinion that the acts of violence were organized with the support of the then Delhi police and some central government officials. Rajiv Gandhi was sworn in as Prime Minister after his mother's death and, when asked about the riots, he said "when a big tree falls, the earth shakes."
