COLOMBO — Sri Lanka's government on Thursday started counting the dead, wounded and missing in its quarter-century civil war amid international pressure to conduct a credible investigation into war crimes allegations. It comes two years after a local war commission recommended a census to determine the number of civilian deaths in the civil war which ended in 2009. Tens of thousands are said to have perished in just the last few months of the fighting. Government census official A.J. Satharasinghe said the countrywide count by some 15,000 workers will be completed on Dec. 20. Sri Lanka is under pressure over its delay to implement the recommendations of the Lessons Learned and Reconciliation Commission which includes a local inquiry into allegations of war abuse against government soldiers and the now-defeated Tamil Tiger rebels. Countries like the United States and Britain have warned that Sri Lanka could face an international war crimes investigation if it fails to conduct its own inquiry. The UN Human Rights Council has passed two successive resolutions calling for an inquiry. UN human rights chief Navi Pillay is expected to submit her findings from a visit to Sri Lanka at the council's next session next March. Sri Lankan troops in May 2009 defeated Tamil Tiger rebels who had fought since 1983 to create an independent state for the country's ethnic minority Tamils. The government expelled international aid workers and UN staff from the war zone in the last stages of the fighting and blocked independent journalists from covering the war, making it impossible for outsiders to know the extent of civilian deaths. According to a UN report, as many as 40,000 Tamil civilians may have died in the last few months of the fighting, which the government disputes. For two years after the war, Sri Lanka's government had insisted that not a single civilian was killed. But later in 2011 it acknowledged some civilian deaths and announced a census of the war dead but its results were vague. Government troops were accused of deliberately shelling civilians, hospitals and blocking food and medical aid to hundreds of thousands of people boxed inside a tiny strip of land as the rebels mounted their last stand. The rebels were accused of holding civilians as human shields, killing those escaped their control and recruiting child soldiers. — AP
