Russian President Vladimir Putin's "special military operation” into Ukraine began on Feb. 24, with troops crossing the border from Belarus and Russia. Moscow's forces have since been met with “stiff resistance” from Ukrainians, according to U.S. officials.
Russian forces retreated last week from the Kyiv suburbs, leaving behind a trail of destruction. After graphic images emerged of civilians lying dead in the streets of Bucha, U.S. and European officials accused Russian troops of committing war crimes.

At least 1,119 civilians killed, 1,790 injured in Ukraine: OHCHR
At least 1,119 civilians have been killed and 1,790 others have been injured in Ukraine since Russian forces invaded on Feb. 24, according to the latest figures from the Office of the United Nations High Commissioner for Human Rights (OHCHR).
At least 99 children were among the dead, according to the OHCHR, which noted that the Prosecutor General's Office of Ukraine had reported at least 139 children were killed as of Sunday.
"Most of the civilian casualties recorded were caused by the use of explosive weapons with a wide impact area, including shelling from heavy artillery and multiple-launch rocket systems, and missile and air strikes," the agency said in a statement Sunday.

The agency noted that the actual number of casualties are believed to be "considerably higher" because the receipt of information from some areas with intense hostilities, like the southeastern port city of Mariupol, have been delayed and many reports are still pending corroboration.
Other areas where the number of casualties are still being corroborated include Volnovakha in the Donetsk Oblast, Izium in the Kharkiv Oblast, Popasna and Rubizhne in the Luhansk Oblast, and Trostianets in the Sumy Oblast, where there are allegations of numerous civilian casualties, according to the OHCHR. Casualty numbers from these regions are not included.
