That's how Ukrainian President Volodymyr Zelensky described the shocking imagesof at least 20 civilian men's bodies strewn across the street in Bucha, northwest of the capital of Kyiv, following the withdrawal of Russian forces from the area.

Accounts of alleged Russian atrocities, including the horrific images of dead civilians captured by Agence France-Presse, are emerging as its forces retreatfrom areas near Kyiv following a failed bid to encircle the capital.

"The elimination of the whole nation, and the people. We are the citizens of Ukraine. We have more than 100 nationalities. This is about the destruction and extermination of all these nationalities," Zelensky said Sunday on CBS News' "Face the Nation" when asked if Russia is carrying out genocide.
