Rajiv Gandhi, the former Indian Prime minister, was assassinated on May 21, 1991, in Sriperumbudur, Chennai, Tamil Nadu, India, by a suicide bomber. In addition to Rajiv Gandhi, at minimum 14 people were slain. It was performed by Thenmozhi Rajaratnam, a leader of the Liberation Tigers of Tamil Eelam, a Sri Lankan Tamil rebel group. At the time, India had recently completed its engagement in the Sri Lankan Civil War through the Indian Peace Keeping Force. Two committees of investigation have investigated later allegations of plot, which have resulted in the downfall of at least one major administration. Gurbachan Singh Manochahal had provided logistical and operational assistance. It was in 2016 that his participation was established.
