* Navi Pillay says accountability needed for Sri Lanka peace * Says U.N. ready to support future inquiry into war crimes * Cites concerns about Pakistan, Afghanistan, Iraq, Colombia By Laura MacInnis GENEVA, June 4 (Reuters) - The United Nations stands ready to support an inquiry into abuses in Sri Lanka's civil war, U.N. High Commissioner for Human Rights Navi Pillay said on Thursday. Addressing the U.N. Human Rights Council, which last week avoided launching an investigation into the Sri Lankan conflict, the former war crimes judge stressed that reconciliation would be impossible without a full reckoning of transgressions. "I believe that accountability is a prerequisite for the attainment of justice and reconciliation for all Sri Lankans and, thus, a foundation for lasting peace," Pillay told the forum. Pillay, who is an ethnic Tamil from South Africa, said the Liberation Tigers of Tamil Eelam (LTTE) and the military both needed to held responsible for killing and mistreating civilians in the last throes of their 25-year conflict. Her remarks sought to keep up pressure on Sri Lanka in spite of the Human Rights Council's failed attempt to scrutinise the conduct of both sides during and after the 25-year separatist war that Colombo declared over last month. Sri Lanka's allies including China, India and Russia backed a resolution it presented to the U.N. body that stressed its sovereign right to act without international interference, and blocked discussion on a Western text expressing concerns about conditions in the country. Human rights groups including Amnesty International have been calling for an outside inquiry as recommended by Pillay. In her Thursday remarks, she also urged Colombo to allow free movement in and out of the camps holding hundreds of thousands of war-displaced people in Sri Lanka's northeast, where the LTTE had been fighting for an independent Tamil homeland in the majority Sinhalese country. She also raised concerns about the welfare of bystanders to other conflicts, including those in Afghanistan and Pakistan where she said international forces needed to do more to protect civilians and investigate non-combatant casualties.
