Mullivaikkal massacre was the mass killing of tens of thousands of Tamil civilians during the final months of the Sri Lankan civil war ending in May 2009 in a tiny strip of land called
Mullivaikkal on the northeast coast of the island, which is part of a larger region known as the
Vanni. The Sri Lankan government designated several No Fire Zones (NFZs) in Mullivaikkal where it had encouraged civilians to concentrate. It then proceeded to shell using heavy weapons three consecutive NFZs killing large numbers of civilians despite having foreknowledge of the impact through information provided by its
UAVs, as well as by the UN and the
ICRC. According to the UN, an estimated 40,000 Tamil civilians were killed, with the majority of casualties being the result of indiscriminate and widespread shelling by the government forces. UN staff had been quoted as saying that by May 2009, up to 1,000 Tamil civilians were being killed each day by the military. In a later
internal review, the UN stated that there was credible information that over 70,000 people are unaccounted for. In February 2009, the Sri Lankan Defence Secretary
Gotabaya Rajapaksa, brother of President
Mahinda Rajapaksa, justified killing Tamil civilians by stating that hospitals operating outside the designated NFZs were legitimate targets; civilians were all "LTTE sympathizers"; and that distinction could not be made between combatants and civilians. In 2014, an international team of investigators for the International Crimes Evidence Project (ICEP) and in 2015 the Report of the
OHCHR Investigation on Sri Lanka (OISL) both found that large numbers of civilians, mostly women and children, queuing at food distribution centers were deliberately killed by government shelling despite there being no
LTTE activity and the government having knowledge of the time and location of the distributions. ICEP found reasonable grounds to believe the shelling of NFZs amounted to
crimes against humanity: murder, extermination, persecution and other inhumane acts. The government was also accused of denying humanitarian assistance by deliberately understating the number of civilians in the conflict zone which resulted in the shortage of food and civilians being starved to death. During the final days of the war, the Sri Lankan Army also engaged in indiscriminate executions of Tamils, civilians as well as fighters who surrendered waving a white flag. Indiscriminate massacres of surrendering civilians, including children, were also carried out at the end of the war on 18 May 2009. A military whistleblower accused government forces of a subsequent cover-up with bodies being buried in mass graves and chemicals being used to dissolve skeletons. A panel of genocide scholars of the
Permanent Peoples' Tribunal described the mass killing in the final stages of the war as the "climax" of the genocidal process.
Francis Boyle, an international lawyer who helped file the
Bosnian genocide case, cited the World Court's 2007 Bosnian Judgment to argue that the "extermination" of Tamil civilians in the Vanni in 2009 numbering many times that of the
Srebrenica massacre "also constituted genocide". Drawing on the parallels between the Srebrenica and the Vanni cases, human rights lawyer Anji Manivannan argued that the Sri Lankan government leaders and military commanders possessed specific intent of genocide in targeting a substantial part of the Tamil population of the Vanni in 2009 for destruction, namely, its numeric size, significance and the presence of the group's leadership; and committed three acts of genocide, namely, killing by intentional shelling of the UN hub, hospitals and food distribution lines; "causing serious bodily or mental harm" by maiming around 30,000 civilians and using sexual violence against hundreds of women and girls; and "deliberately inflicting conditions of life to bring about the group's physical destruction" by denying humanitarian aid. Professor Jude Lal Fernando situated the genocidal intent and actions of the Sri Lankan state during the Mullivaikkal massacre within the historical context of a
majoritarian nation-building process, and argued that the Sri Lankan state is motivated by
Sinhalese Buddhist nationalism which underpinned its intent to destroy the Tamil ethnic group in part. Fernando cited statements from Sri Lankan military and political leaders who claimed the island as a Sinhalese country and denied the civilian status of Tamil civilians trapped in the war zone by describing them as "just the relatives of the Terrorists" as reflecting the genocidal intent of the state. Tamil human rights group
PEARL published a report in September 2024 arguing that there was a sufficient legal basis to describe the massacre as a genocide. It stated that the Sri Lankan government was guilty of the first three acts of genocide as listed in the
Genocide Convention; and that they were committed with
genocidal intent to destroy in part the Tamil people. It argued that the targeted part, Tamils of the Vanni, constituted a "substantial part" of the whole Tamil population in Sri Lanka; and based on the UN and ITJP figures, it estimated that 1.3 and 5.5 percent, respectively, of the whole Tamil population (
Indian Tamils) in Sri Lanka and 13 and 57 percent, respectively, of the whole Tamil population of the Vanni itself were killed in the massacre. Following the precedent set by
ICTR,
ICTY and
UN Fact-Finding Mission on Myanmar, it argued that genocidal intent can be inferred from circumstantial evidence, such as disproportionate and systematic use of force against Tamils in the Vanni and statements of Defence Secretary conflating civilians with combatants. Research scholar Karthick Ram Manoharan argued that the Sri Lankan state adopted genocide as a
counterinsurgency strategy against the Tamil population and its genocidal intentions were rooted in Sinhalese nationalism that claims the entire island as an exclusive Sinhalese property and seeks to assimilate Tamils through "
Sinhalization". Former UN staffer Benjamin Dix, who had worked in the Vanni between 2004 and 2008, stated it was a "very fair" assessment that the Sri Lankan Army committed genocide, describing the final offensive as "destruction of the Tamil community". Several other authors and journalists have also described the massacre as a genocide.
Eyewitness accounts On 18 May 2010,
Channel 4 News broadcast interviews with two Sri Lankan soldiers who claimed that they had been given orders from "the top" to summarily execute
all ethnic Tamils, civilians as well as fighters. A senior commander claimed "the order would have been to kill everybody and finish them off...It is clear that such orders were...from the top". Sri Lankan Defence Secretary Gotabaya Rajapaksa was said to have given direct orders to army commanders at the battle front. The commander also claimed that
Velupillai Prabhakaran's 12-year-old son
Balachandran was interrogated by the military before being shot dead. A front line soldier said, "our commander ordered us to kill everyone. We killed everyone". The soldier claimed that the Tamils were tortured before being executed. Numerous photos taken by Sri Lankan soldiers showing dead bodies and Tamil prisoners were also shown in the broadcast. One of the soldiers who served in the 58 Division of the
Sri Lankan Army tearfully recounted the heinous crimes committed by fellow soldiers in 2009: He further described the government's attempts to cover up: {{Blockquote An army insider also witnessed indiscriminate massacres on 18 May 2009, and stated the following: {{Blockquote
UN response In a 2012
internal review of its conduct during the last stages of the Sri Lankan civil war, the
UN found that various UN agencies had failed to protect Tamil civilians at every level, particularly by withdrawing its staff from the war zone and by withholding evidence of widespread government shelling.
Vijay Nambiar, then chief of staff under UN Secretary-General, implored
Navi Pillay (High Commissioner for Human Rights) to dilute her statement on potential war crimes by the government, complaining that it put the LTTE and the government "on the same footing". Commenting on Nambiar's statement that UN's role should be "compatible with the government," Francis Boyle, professor of international law, denounced the UN and its top officials as aiding and abetting Tamil genocide. Vijay Nambiar's own brother
Satish Nambiar was a consultant to the Sri Lankan government and had praised the Sri Lanka Army and its conduct of the war, in spite of all the civilians killed.
Louise Arbour, the former UN High Commissioner for Human Rights, described the UN's conduct as having "verged on complicity". The UN's response was constrained by some of its powerful
veto-wielding members such as China and Russia who shielded the Sri Lankan government. In 2016 then UN Secretary-General
Ban Ki-moon acknowledged UN's failures in Sri Lanka which he named along with
Rwanda and
Srebrenica as examples of its "never again" repeating itself. == Sexual violence ==
