At least 6,595 Ukrainian civilians have been killed and 10,189 injured since Russia invaded the country in February, according to the Office of the United Nations High Commissioner for Human Rights (OHCHR).
Among those killed were at least 415 children, 2,575 men, 1,767 women and 1,838 other adults whose gender is yet to be identified, according to data released Monday's figures.
Many of the civilian casualties have occurred in the Donetsk and Luhansk regions in the Donbas -- an eastern region at the heart of the war that has seen the most intense fighting in recent months.
The OHCHR report said 3,939 civilians were killed and 5,338 others injured in Donetsk and Luhansk, including 449 in Russian-controlled territory.
The commission said actual figures are “considerably higher” due to a lack of or delayed information in areas where the conflict has intensified, including in cities such as Mariupol, Izium, Lysychansk, Popasna and Severodonetsk.
Most of the casualties recorded were a result of explosive weapons with wide area effects such as shelling from heavy artillery, multiple launch rocket systems, missiles and air strikes, the report added.
