Civilian casualties from February 24, when Russia launched the war against Ukraine, to 24:00 on April 6 were 3,838 civilians (3,776 in a summary a day earlier), including 1,611 deaths (1,563), the UN High Commissioner for Human Rights said Thursday.

"OHCHR believes that the actual figures are significantly higher because information from some places where intense fighting has taken place has been delayed and many reports are still awaiting confirmation," the document said.

According to it, this applies, for example, to Mariupol and Volnovakha (Donetsk region), Izyum (Kharkiv region), Popasna (Luhansk region), and Borodyanka (Kyiv region), where there are reports of numerous civilian casualties. They are subject to further verification and are not included in the above statistics.

"The majority of civilian deaths or injuries were caused by the use of explosive devices with a wide kill zone, including heavy artillery and multiple rocket launchers, as well as missile and air strikes," the report said.

The UN confirmed that 409 men, 240 women, 43 boys and 25 girls were killed, while the gender of 63 children and 831 adults could not yet be determined.

The 2,227 wounded include 45 girls and 42 boys, as well as 104 children whose sex could not yet be determined.

Compared to the previous day, according to the UN, one child was killed and three others were wounded.

The UN OHCHR indicates that as of midnight on April 7, there were 425 (420) deaths and 833 (821) injuries in government-controlled territory and 67 (67) deaths and 259 (259) injuries in territory controlled by self-proclaimed "republics" in Donetsk and Luhansk regions.

In other regions of Ukraine under government control (Kyiv, as well as Zhytomyr, Zaporizhzhia, Kyiv, Sumy, Odesa, Mykolaiv, Kharkiv, Kherson, Dnipropetrovsk, Cherkasy and Chernihiv regions) the UN recorded 1,119 (1,076) dead and 1,135 (1,133) wounded.

The report also says that according to the Office of the Prosecutor General of Ukraine, as of 8:00 a.m. on April 7, 167 (167) children were killed and 297 (279) wounded.

The increase in the figures in this summary compared to the figures in the previous summary should not be attributed only to the new cases that took place on April 6, as during the day, the OHCHR also verified a number of cases that took place in previous days, the document specifies.
