A human rights group in Sri Lanka has blamed local security forces for the massacre of 17 aid workers in 2006 and accused the government of a cover-up. The bodies of the Action Against Hunger workers were found in the north-eastern town of Muttur. It was one of the worst attacks on humanitarian workers since the 2003 bombing of the UN compound in Baghdad. Meanwhile, another human rights group has shut down, after accusing Colombo of failing to tackle rights issues. So far there has been no response from the government to both developments.
