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.

More than 3.9 million people have been forced to flee Ukraine since Russian forces invaded on Feb. 24, according to the latest figures from the United Nations Refugee Agency.
The tally from the U.N. High Commissioner for Refugees (UNHCR) amounts to just over 8.8% of Ukraine's population -- which the World Bank counted at 44 million at the end of 2020 -- on the move across borders in 34 days.
More than half of the refugees crossed into neighboring Poland, UNHCR figures show.

Russia's "special military operation" in Ukraine will continue "until the objectives are achieved," Russian Defense Minister Sergei Shoigu said Tuesday.
Shoigu claimed that Russian troops are "actively providing humanitarian assistance to the population of" the self-declared Donetsk and Luhansk people's republics as well as Ukraine.
"As many as 684 humanitarian operations have been completed and 6,079 tons of cargo have been supplied to 210 populated localities," Shoigu said at a teleconference.
Russian forces struck Mykolaiv's regional state administration building on Tuesday morning, Ukrainian authorities said.
A video posted on Telegram by Mykolaiv Oblast Gov. Vitaliy Kim and verified by ABC News shows the moment the building was hit. A live webcam over the southern city of Mykolaiv captured the missile crossing the camera. Moments later, smoke from an explosion fills the screen.
Another video posted on Facebook by the State Emergency Service of Ukraine and verified by ABC News shows a gaping hole in the building where the missile hit. At least seven people were killed and 22 others were injured. Search and rescue operations are ongoing, according to the State Emergency Service.
An image posted on Twitter by Ukraine's Center for Strategic Communication and Information Security (Stratcom) also showed the destroyed building.
