1991 massacre in Sriperumbudur, India
The assassination of Rajiv Gandhi, former prime minister of India, occurred as a result of a suicide bombing in Sriperumbudur in Tamil Nadu, India on 21 May 1991. At least 14 others, in addition to Gandhi and the assassin, were killed. It was carried out by 22-year-old Kalaivani Rajaratnam (popularly known by her assumed names Thenmozhi Rajaratnam and Dhanu), a member of the banned Sri Lankan Tamil separatist rebel organization Liberation Tigers of Tamil Eelam (LTTE). At the time, India had just ended its involvement, through the Indian Peace Keeping Force, in the Sri Lankan Civil War.
Subsequent accusations of conspiracy have been addressed by two commissions of inquiry and have brought down at least one national government, the government of Inder Kumar Gujral.
Attack and death.
Rajiv Gandhi campaigned on behalf of the Indian National Congress and its state affiliates, such as the Tamil Nadu Congress Committee, in the 1991 Indian general election. On 21 May, after campaigning in Visakhapatnam, Andhra Pradesh, his next stop was Sriperumbudur, Tamil Nadu. About two hours after arriving in Madras (now Chennai), Gandhi was driven by motorcade in a white Ambassador car to Sriperumbudur, stopping along the way at a few other election campaigning venues. Neena Gopal of the "Gulf News of Dubai" was also in the car, in the back seat with a local candidate, Maragatham Chandrasekar. 
When Gandhi reached a campaign rally in Sriperumbudur, he left his car and began walking towards the dais where he was to deliver a speech. Along the way, he was garlanded by many well-wishers, Indian National Congress workers and school children. The assassin, Kalaivani Rajaratnam, approached and greeted him. She then bent down to touch his feet and detonated an RDX explosive-laden belt tucked below her dress at exactly 10:10 PM. Gandhi, Rajaratnam and 14 others were killed in the explosion that followed, along with 43 others who were grievously injured. The assassination was caught on film by a local photographer, Haribabu (also a conspirator), who also died in the blast but whose camera and film was found intact at the site.
Victims.
Apart from former Prime Minister Rajiv Gandhi and the suicide bomber Kalaivani Rajaratnam, 15 people perished in the blast:
Around 43 bystanders, including police sub-inspector Anushiya Daisy, were injured in the explosion; there were 59 casualties in total.
Security lapses.
The Supreme Court held that the decision to eliminate Gandhi was precipitated by his interview with "Sunday" magazine (21–28 August 1990), where he stated that he would send the IPKF to disarm the LTTE if he returned to power. Gandhi also defended the signing of the Indo-Sri Lanka accord in the same interview. The LTTE's decision to kill him was perhaps aimed at preventing him from coming to power again. Thereafter, the Justice J. S. Verma Commission was formed to look into the security lapses that contributed to the killing.
The final report, submitted in June 1992, concluded that the security arrangements for the former PM were adequate but that the local Congress party leaders disrupted and broke these arrangements.
The findings raised vital questions that political analysts have consistently raised. The Narasimha Rao government initially rejected Verma's findings but later accepted it under pressure. However, no action was taken on the recommendations of the commission.
Sources have indicated that Gandhi was repeatedly informed that there was a threat to his life and that he should not travel to Tamil Nadu. The then governor of Tamil Nadu Bhishma Narain Singh, broke official protocol and twice warned Gandhi about the threat to his life if he visited the state.
Subramanian Swamy said in his book, "Sri Lanka in Crisis: India's Options (2007)", that an LTTE delegation had met Rajiv Gandhi on 5 March 1991. Another delegation met him around 14 March 1991 in New Delhi.
Journalist Ram Bahadur Rai wrote that:
The message conveyed to Rajiv Gandhi by both these delegations was that there was no threat to his life and he could travel to Tamil Nadu without fearing for his life. I did a series of articles after his assassination that pointed out how, after these meetings, Rajiv became complacent about his security and broke security rules in more than 40 rallies.
Funeral.
Following his assassination, Rajiv Gandhi's mutilated body was airlifted to New Delhi. From the Indira Gandhi International Airport, his body was sent to the All India Institute of Medical Sciences in New Delhi for an autopsy, reconstruction and embalming.
A state funeral was held for Rajiv Gandhi on 24 May 1991. His funeral was broadcast live nationally and internationally and was attended by dignitaries from over 60 countries. He was cremated on the banks of the river Yamuna, near the cremation spot of his mother, brother and grandfather. Today, the site where he was cremated is known as Veerbhumi.
Investigation.
Immediately after the assassination, the Chandra Shekhar government handed the investigation over to the CBI on 22 May 1991. The agency created a special investigation team (SIT) under D. R. Karthikeyan to determine who was responsible for the assassination. The SIT probe confirmed the role of the LTTE in the assassination, which was upheld by the Supreme Court of India.
The Commission report stated that the year 1989 signified "the perpetuation of the general political trend of indulging the Tamil militants on Indian soil and tolerance of their wide-ranging criminal and anti-national activities". The report also alleged that LTTE leaders in Jaffna were in possession of sensitive coded messages exchanged between the Union government and the state government. "There is evidence to show that, during this period, some of the most vital wireless messages were passed between the LTTE operatives based in Tamil Nadu and Jaffna. These messages, which were decoded later, are directly related to the assassination of Rajiv Gandhi", the report stated. The Congress subsequently brought down the United Front (UF) government of I K Gujral after the report was leaked in November 1998.
Perpetrator.
The assassination was carried out by Kalaivani Rajaratnam alias Dhanu. She was born on 26 July 1968 in Kaithady Nunavil, Jaffna Peninsula. It was after joining the LTTE that she came to be known by the assumed name Thenmozhi. Her family hailed from Kupukullai, a small village in Jaffna. She studied in Vavuniya and Batticaloa. She also temporarily lived in Urumpirai. She was inspired by the Tamil militant group Liberation Tigers of Tamil Eelam (Tamil Tigers) at a young age, and joined the Black Tigers (suicide bombers) after an ankle injury. She was known as “"captain Akino"” and was a flag bearer for female LTTE marches. Another reason why Kalaivani became a Tiger is that her brother was a well-known cadre who had died and she was carrying on the family tradition.
Kalaivani was the daughter of a Sri Lankan Tamil man named A. Rajaratnam and his second wife. A. Rajaratnam's first wife died during childbirth in 1962, when he was visiting tea estates. Rajaratnam was described as Velupillai Prabhakaran's mentor, and he played a vital role in moulding the LTTE chief's thinking during the movement's formative years between 1972 and 1975. A. Rajaratnam died in 1975 when Kalaivani was 7; he was in Chennai, and his body was airlifted to Jaffna, where his funeral was held. Marital status of Kalaivani at the time of her death, is not known to the general public. Kalaivani was survived by her mother, brother Sivavarman and two sisters, Anuja and Vasugi, the former died in a skirmish with the Indian army in Weli Oya in late 1991 and the latter moved to France.
Kalaivani is related to Sivarasan and Subha, two co-conspirators of the plot. Sivarasan's mother, Sivapackiyam was the sister of Kalaivani's father whereas Subha's parents are related to Sivarasan's father. Another assumed reason as to why they were selected to assassinate Rajiv Gandhi was due to the genetics of the Rajaratnam-Pillai clan, of which many exhibited drastically different front and side profiles.
The court convicted and sentenced the seven persons who facilitated the assassination of Rajiv Gandhi to life imprisonment. On November 11, 2022, the Supreme Court of India ordered the release of six convicts in the 1991 Rajiv Gandhi assassination case, after the Tamil Nadu government controversially recommended their remission in March 2016, the convicts are:
Supreme Court judgment.
As per the Supreme Court of India judgment, by Judge K. T. Thomas, the killing was carried out due to personal animosity of the LTTE chief Prabhakaran towards Rajiv Gandhi arising from his sending the Indian Peace Keeping Force (IPKF) to Sri Lanka and the numerous war crimes perpetrated by IPKF personnel against Sri Lankan Tamils. Additionally, the Rajiv Gandhi administration had antagonised other Tamil militant organisations like PLOTE for reversing the military coup in Maldives back in 1988.
The judgment further cited the death of Thileepan in a hunger strike and the suicide by 12 LTTE cadres in a vessel in October 1987. While convicting the accused, four of them to death and others to various jail terms, the judgment stated that no evidence existed that any one of the conspirators ever desired the death of any Indian other than Rajiv Gandhi, though several others were killed. Judge Wadhwa further stated there was nothing on record to show that the intention to kill Rajiv Gandhi was to overawe the government. Hence it was held that it was not a terrorist act under TADA (Act). Judge Thomas further stated that conspiracy was hatched in stages commencing from 1987 and that it spanned several years. The special investigation team of India's premier special investigation agency Central Bureau of Investigation was not able to pinpoint when the decision to kill Rajiv Gandhi was taken.
Trial.
The trial was conducted under the Terrorist and Disruptive Activities Act. On 28 January 1998, the designated TADA court in Chennai gave death sentences to all the 26 accused. This created a storm in India. Legal experts were divided. Human rights groups protested that the trial did not meet the standards of a free trial. The trial was held behind closed doors, "in chambers", and the identity of witnesses was not disclosed. Ms A. Athirai, an accused, was 17 years old when she was arrested.
Under the TADA an accused can appeal only to the Supreme Court. Appeal to the High Court is not allowed as in normal law. Confessions given by the accused to the Superintendent of Police are taken as evidence against the accused under TADA. Under TADA the accused could be convicted based on evidence that would have been insufficient for conviction by an ordinary court under normal Indian law. In the Rajiv Gandhi case, confessions by the accused formed a major part of the evidence in the judgment against them which they later claimed was taken under duress.
On appeal to the Supreme Court, only four accused were sentenced to death and the others to various jail terms. S. Nalini Sriharan is the lone surviving member of the five-member squad behind the assassination of Rajiv Gandhi and is serving life imprisonment. Arrested on 14 June 1991, she was sentenced to death, along with the other 25 accused. However, the court confirmed that the death sentence was given to only four of the convicts, including Nalini, on 11 May 1999. Nalini, who is the wife of an LTTE operative known as V. Sriharan alias Murugan, another convict in the case who had been sentenced to death, later gave birth to a girl, Harithra Murugan in prison. Upon the intervention of Rajiv Gandhi's widow and Congress president Sonia Gandhi, who petitioned for clemency for the sake of Nalini's daughter in 2000, the death sentence was commuted to life imprisonment. Nalini was treated as a class 'A' convict from 10 September 1999 till the privilege was withdrawn in May 2010 after a mobile phone was allegedly recovered from her cell during a surprise check. She "regrets" the killing of the former Prime Minister and claims that the real conspirators have not been booked yet. The President of India rejected the clemency pleas of Murugan and two others on death row, T Suthendraraja alias Santhan and A G Perarivalan alias Arivu in August 2011. The execution of the three convicts was scheduled for 9 September 2011. However, the Madras High Court intervened and stayed their execution for eight weeks based on their petitions. Nalini was shifted back to Vellore prison from Puzhal prison amidst tight security on 7 September 2011. In 2010, Nalini moved the Madras
