Nov 13 (BBC) The United Nations failed in its mandate to protect civilians in the last months of Sri Lanka's bloody civil war, a leaked draft of a highly critical internal UN report says.
"Events in Sri Lanka mark a grave failure of the UN," it concludes.
The government and Tamil rebels are accused of war crimes in the brutal conflict which ended in May 2009.
The UN does not comment on leaked reports and says it will publish the final version.
The 26-year war left at least 100,000 people dead. There are still no confirmed figures for tens of thousands of civilian deaths in the last months of battle. An earlier UN investigation said it was possible up to 40,000 people had been killed in the final five months alone. Others suggest the number of deaths could be even higher.
Former senior UN official Charles Petrie, who headed the internal review panel, told the BBC the "penultimate" draft the BBC has seen "very much reflects the findings of the panel". He is now in New York to present the report to the UN Secretary General Ban Ki-moon.
Sources say a brief executive summary, which sets out the panel's conclusions in stark terms, has been removed in a final report which will number about 30 pages, with additional detailed annexes.
UN spokesman Martin Nesirky told the BBC the UN does not comment on leaked reports. He said a final version would be published once the secretary general had received and read it.
Senior UN sources say Ban Ki-moon is determined to act on its wide-ranging recommendations in order to "learn lessons" and respond more effectively to major new crises such as Syria now confronting the international community.
The UN's investigation into its own conduct during the last months of the conflict says the organisation should in future "be able to meet a much higher standard in fulfilling its protection and humanitarian responsibilities".
It points to a "systemic failure".
The panel questions decisions such as the withdrawal of UN staff from the war zone in September 2008 after the Sri Lankan government warned it could no longer guarantee their safety.
Benjamin Dix, who was part of the UN team that left, says he disagreed with the pullout.
"I believe we should have gone further north, not evacuate south, and basically abandon the civilian population with no protection or witness," Mr Dix told the BBC.
"As a humanitarian worker, questions were running through my mind 'what is this all about? Isn't this what we signed up to do?'"
Hundreds of thousands of Tamil civilians remained in the war zone, exploited by both sides: forcibly recruited by Tamil Tigers or used as human shields; or under indiscriminate government fire.
"We begged them, we pleaded with them not to leave the area. They did not listen to us," said a Tamil school teacher now seeking asylum in Britain, who did not want to be named. "If they had stayed there, and listened to us, many more people would be alive today."
Despite a "catastrophic" situation on the ground, this report bluntly points out that in the capital Colombo "many senior UN staff did not perceive the prevention of killing of civilians as their responsibility - and agency and department heads at UNHQ were not instructing them otherwise".
It says there was "a sustained and institutionalised reluctance" among UN personnel in Sri Lanka "to stand up for the rights of people they were mandated to assist".
'Culture of trade-offs'
Citing detailed records of meetings and reports, the review highlights how the UN did not publish mounting civilian casualty figures even though a detailed annex makes clear there was a "rigorous methodology."
Under intense pressure from the Sri Lankan government, it also did not make public that "a large majority" of deaths were caused by government shelling. The government repeatedly denied it shelled civilian areas.
How did the UN failure happen? The report explores at length how senior staff in Colombo "had insufficient political expertise and experience in armed conflicts and in human rights... to deal with the challenge that Sri Lanka presented", and were not given "sufficient policy and political support" from headquarters. It also points to the Sri Lankan government's "stratagem of intimidation", including "control of visas to sanction staff critical of the state".
The result was a UN system dominated by "a culture of trade-offs" - UN staff chose not to speak out against the government in an effort to try to improve humanitarian access.
Edward Mortimer, a former senior UN official who now chairs the Sri Lanka Campaign for Peace and Justice, says UN staff left when the population needed them more than ever.
"I fear this report will show the UN has not lived up to the standards we expect of it and has not behaved as the moral conscience of the world," Mr Mortimer said.
