The human rights group Amnesty International has released a new report criticizing Kyrgyz authorities for being "unwilling or unable to investigate allegations of complicity or collusion of security forces" in the deadly violence in the city of Osh two years ago.
More than 400 people were killed and tens of thousands displaced during fighting between Kyrgyz and ethnic Uzbeks.
The majority of casualties were among Uzbeks, and there were reports that the mainly ethnic Kyrgyz security and law-enforcement personnel may have aided fellow Kyrgyz citizens during the days of violence.
Amnesty International said crimes against humanity that included "torture, rape, and murder" in the violence have gone unpunished.
The report says "truth, accountability, and justice are the only tools that will mend the bridges between the two ethnic communities."
