Ukrainian President Volodymyr Zelenskyy will address the U.N. Security Council for the first time Tuesday at a meeting that is certain to focus on what appear to be widespread deliberate killings of civilians by Russian troops.
The dead were discovered after the withdrawal of Russian forces from a town on the outskirts of the capital, Kyiv, and have sparked global outrage and vehement denials from the Russian government that it was responsible.
