The United Nations says the number of people killed in eastern Ukraine has nearly doubled over the past two weeks.
Cecile Pouilly, a spokeswoman for the UN human rights office, said on Wednesday that figures show the death toll has now passed 2,086, up from 1,129, which was recorded on July 26.
The UN official added that at least 20 children were among the victims.
More than 4,950 people have also sustained injuries in the fighting since mid-April.
Pouilly said that on average more than 60 people died or sustained injuries per day as part of “a clear escalating trend” of violence.
In the latest developments, pro-Russia activists killed at least 12 pro-Kiev fighters battling alongside government forces.
The pro-Russians also took captive an unknown number of nationalist fighters outside the eastern city of Donetsk.
It was a major fatality figure for the pro-Kiev fighters since the crisis began in Ukraine in April.
Ukraine’s mainly Russian-speaking regions in the east have witnessed deadly clashes between pro-Russia protesters and the Ukrainian army since the government in Kiev launched military operations to silence pro-Russians.
According to the United Nations, nearly 300,000 people have been forced to flee their homes due to fierce fighting in eastern Ukraine.
The Ukrainian army is also trying to take control of the eastern city of Luhansk, where the living conditions have sharply deteriorated.
