Q. Which PM was killed

Indira Gandhi and Rajiv Gandhi are the two Indian Prime Ministers who were assassinated while in or after holding office. Indira Gandhi was assassinated on October 31, 1984, by two of her own Sikh bodyguards, Beant Singh and Satwant Singh, in retaliation for Operation Blue Star—the military action she ordered to remove Sikh militants from the Golden Temple in Amritsar. She was shot approximately 31 times in her garden at 1 Safdarjung Road in New Delhi and died later that day at the All India Institute of Medical Sciences. Her assassination triggered widespread anti-Sikh riots across India, resulting in thousands of deaths, particularly in Delhi.

Rajiv Gandhi, who succeeded his mother as Prime Minister, was assassinated on May 21, 1991, by a Liberation Tigers of Tamil Eelam (LTTE) suicide bomber during an election campaign rally in Sriperumbudur, Tamil Nadu. The assassination was carried out by Thenmozhi Rajaratnam (also known as Dhanu), who detonated an explosive device hidden in a belt when Rajiv Gandhi bent down to greet her. The attack killed Rajiv Gandhi along with several others present at the rally. The assassination was linked to his government's decision to send the Indian Peace Keeping Force to Sri Lanka in 1987-1990, which had angered the LTTE. Both assassinations profoundly impacted Indian politics, raised serious questions about security protocols for high-ranking officials, and highlighted the violent consequences of complex political and communal tensions in the region.
