Ukrainian President Volodymyr Zelenskyy, addressing the U.N. Security Council on  Tuesday, emphasized the apparent massacre of civilians by Russian forces in and around Kyiv and other major cities in pleading for war crime charges against Russian leaders.

Zelenskyy reaffirmed that Ukrainian forces that retook cities found mass graves, revelations of atrocities and infrastructure destroyed by Russian forces.

“They killed entire families, adults and children, and they tried to burn their bodies,” Zelenskyy said of the Russian invaders.

Zelenskyy urged the U.N. to provide security guarantees to Ukraine.

“What is the purpose of our organization? Its purpose is to maintain peace,” Zelenskyy said. “And now the U.N. Charter has been violated, starting with Article 1. What is the point of all the other articles?”

Human Rights Watch: Russia using banned mines

Russian forces are using banned anti-personnel mines as they pull back from cities in Ukraine, a Human Rights Watch report says. The report was followed this week by the discovery of the bodies of more than 400 civilians in areas around Kyiv, some in mass graves. Russia is using a device known as the Pom-3 Medallion, a mine capable of killing people within a 50-foot radius, Human Rights Watch said.
