Sri Lanka commemorated the ninth anniversary of the end of its civil war as a divided nation, with minority Tamils calling for an international investigation into alleged wartime atrocities and the government defending soldiers from allegations. President Maithripala Sirisena on Saturday presided over a war memorial ceremony in the capital, Colombo. He said even though some accuse the military of war crimes, such allegations have not been formally levied by world bodies such as the UN Human Rights Council. The Office of the UN High Commissioner for Human Rights in a 2015 report said if allegations against both the government forces and separatist Tamil Tigers could be established in a court of law, they may, depending on the circumstances, amount to war crimes. Sirisena said there were no proper records to show the number of civilians who died in the 26-year civil war but said it could be around 100,000. The UN initially estimated the death toll at the same number, but it is suspected to be much higher since there were no independent witnesses to the final year of fighting. The government pledged in 2015 to carry out an impartial investigation into alleged war crimes, but has taken no action so far. In his remarks, Sirisena said his government remained on the path to ethnic reconciliation. At a ceremony held on Friday, C.V. Wigneswaran, chief minister of Tamil-dominated Northern Province, called for an international investigation into civilian deaths during the war. “The international community without delay should set up an international strategic mechanism to ensure justice for the people affected,” Wigneswaran said speaking in Mullivaikkal village, the scene of the final battle. He also called for every May 18 to be observed as “Tamil Genocide Day” and for the withdrawal of Sri Lankan armed forces from the former war zones. In the first few years after the end of the war, Sri Lanka’s government barred civilians from remembering their dead and instead, held grand victory ceremonies with parading soldiers and military ware and conducting air shows. However, Sirisena, who was elected in 2015 on a platform of post-war ethnic reconciliation, has limited the victory ceremony to honouring soldiers while allowing Tamils also to remember their dead. Sri Lankan troops defeated the Tamil Tiger rebels in 2009, ending more than a quarter-century of separatist civil unrest. Both sides were accused of serious human rights violations. The government was accused of deliberately targeting civilians, hospitals and blocking food and medicine for the people boxed in the war zone. The Tamil Tigers were accused of conscripting child soldiers, holding civilians as human shields and killing those trying to escape from their control.
