The eight-member commission in Sri Lanka has completed its first day of hearings, investigating conducts during the last years of the war between government forces and Tamil Tiger rebels. Its members have been appointed by the government. There have been calls for a fuller international enquiry amid claims that Sri Lanka's military killed tens of thousands of civilians in the final stage of the war.Meanwhile, fifty-seven members of the United States Congress have written to the Secretary of State Hillary Clinton urging her to push for an independent international investigation into allegations of war crimes in the island nation. They said the Commission set up by the Sri Lankan government lacks credibility.
