Kyrgyzstan is marking two years since deadly ethnic clashes in the country's south left more than 400 people dead and many thousands more displaced.
The Kyrgyz government has declared June 10 National Remembrance Day, with Prime Minister Omurbek Babanov and other government ministers due to attend a memorial rally in the capital, Bishkek.
Fears of fresh violence have prompted tight security measures in the southern city of Osh, the site of some of the worst clashes in 2010.
Checkpoints have been placed on incoming roads, and police are conducting passport checks inside the city.
A new report issued by Russia's Memorial, the Norwegian Helsinki Committee, and the U.S.-based Freedom House says many details remain unknown about the sudden outbreak of violence between Kyrgyz and ethnic Uzbeks.
