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.

Asked by a reporter on the papal plane taking Francis from Rome to Malta if he was considering an invitation made by Ukrainian political and religious authorities, Francis answered: "Yes, it is on the table." He gave no further details.
The pope didn’t mention Russian President Vladimir Putin by name during his remarks, but said "some potentate" had unleashed the threat of nuclear war on the world in an "infantile and destructive aggression" under the guise of "anachronist claims of nationalistic interests."
"We had thought that invasions of other countries, savage street fighting and atomic threats were grim memories of a distant past," Francis added.

Zelenskyy says Russian forces are leaving behind 'a catastrophic situation'
Ukrainian President Volodymyr Zeleneksyy claimed Russian forces are leaving behind "a catastrophic situation" and that they are mining the entire territory.
"Occupiers are retreating in the north of our country, slowly but noticeably. Somewhere they are pushed away with fighting, somewhere they are leaving their positions themselves. After their withdrawal, the situation is catastrophic, and there is so much danger," Zelenskyy said.
Zelenskyy then claimed, "First of all, airstrikes might continue. Secondly, they are mining the entire territory, houses, hardware, even the bodies of those killed. There are so many tripwires and other dangers."

He warned that people returning to these territories should be careful as "it's still not possible to return to normal life as it used to be, even at the territories that we are taking back after the fighting. We need wait till our land is de-mined, wait till we are able to assure you that there won't be new shelling."
Zelenskyy claimed Ukrainians have been able to evacuate 6,266 people, including 3,071 residents of Mariupol. He also said they are discussing the evacuation of the injured and killed military personnel and civilians, with Turkey acting as an intermediary.
Zelenskyy said Russian troops are preparing for new "powerful strikes" in the east and warned that Russia is trying to conscript people in Crimea.
Zelenskyy, speaking in Russian, addressed the Russian people, asking them to, "Warn every conscript and their parents that we don't need more killed people here. Take care of your children so that they don't turn into evil. Don't let them go to the army. Do whatever you can to let them live at home, at their home."

US cancels ballistic missile test to avoid escalation with Russia
A U.S. intercontinental ballistic missile test that was initially postponed in early March to avoid "misinterpretation" by Russia was recently canceled, the Department of the Air Force said Friday.
Defense Secretary Lloyd Austin originally delayed the routine test flight of an LGM-30G Minuteman III missile after Russia put its nuclear deterrent forces on a state of heightened alert.
"The launch had been previously delayed due to an overabundance of caution to avoid misinterpretation or miscommunication during the ongoing Russian invasion of Ukraine and was cancelled for the same reason," the Air Force said in a statement. "Our next planned test flight is later this year. The Department is confident in the readiness of the strategic forces of the United States."
