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.
