KYIV — Some 13,000 people have been killed, a quarter of them civilians, and as many as 30,000 wounded in the war in eastern Ukraine since it broke out in April 2014, the United Nations says.

The estimated toll includes more than 3,300 civilian deaths, the UN Office of the High Commissioner for Human Rights (OHCHR) said in a document dated February 25 and provided to RFE/RL the same day.

It comes as the simmering conflict between Russia-backed separatists and government forces approaches its sixth year, with little progress toward the implementation of a Western-brokered cease-fire and political-settlement deal known as the Minsk Accords.
