Ukrainian President Volodymyr Zelensky addressed the United Nations Security Council on Tuesday after warning that newly uncovered atrocities following the withdrawal of Russian forces near Kyiv could be worse than those in the city of Bucha, where he said more than 300 civilians have been tortured or killed.
The scale of the killings prompted Western leaders to vow a wide-ranging investigation into alleged war crimes and impose further penalties on Moscow as international outrage grows. President Biden on Monday called for a war-crimes trial over the accounts of rape and the killing of civilians in Bucha and other towns that had been occupied by Russian forces, saying that President Vladimir Putin must be held accountable.
