UN 'failed to protect civilians in final months of Sri Lanka civil war' The draft, which was obtained by the BBC, said the events marked "a grave failure" of the UN, adding that the organisation should "be able to meet a much higher standard in fulfilling its protection and humanitarian responsibilities." Sri Lankan forces finally crushed Tamil rebels in May 2009 following decades of brutal fighting. The conflict claimed up to 100,000 lives, according to UN estimates, and both sides are accused of war crimes. At UN headquarters in New York, the report continues, "engagement with member states regarding Sri Lanka was heavily influenced by what it perceived member states wanted to hear, rather than by what member states needed to know if they were to respond." The internal panel also questioned the UN's decision to pull out its staff from the Sri Lankan war zone in September 2008 after the government warned it could no longer guarantee their safety. Benjamin Dix, who was part of the UN team that left, was against the pullout. "I believe we should have gone further north, not evacuate south, and basically abandon the civilian population with no protection or witness," 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?' Senior UN sources told the BBC that UN Secretary General Ban Ki-moon was determined to act on the report's recommendations in order to "learn lessons" from Sri Lanka and respond more effectively to new international crises such as the bloodshed in Syria. The UN told the BBC that it did not comment on leaked reports and that it would publish the final version.
