The United Nations' human rights office said more than 9,000 people have died in 21 months of fighting in eastern Ukraine, even though there has been a "sharp de-escalation of hostilities" since August.
The United Nations High Commissioner for Human Rights said in its report released Wednesday that the withdrawal of heavy weapons following a new September 1 truce agreement has been instrumental in calming violence between Ukrainian government forces and pro-Russian separatists.
But the report cautioned that skirmishes in early November may be early warning of an uptick in violence.
Wednesday's report covered mid-August to mid-November 2015.
It said at least 9,098 people, including fighters and civilians, have died since the violence erupted last year.
