Zelenskyy tells the United Nations Security Council to punish Russia or 'dissolve yourself altogether'

Ukrainian President Volodymyr Zelenskyy railed against the United Nations' ineffectiveness to stop Russia's ongoing war in a speech to the Security Council on Tuesday.

Zelenskyy told the UN Security Council (UNSC) that he sees two options for the group following the discovery of mass civilian killings in the Kyiv suburb of Bucha: punish Russia or dissolve itself.

The Ukrainian leader urged the UNSC to remove Russia, which is a permanent member of the council, "as an aggressor and a source of war so it cannot block decisions about its own aggression."

Or, he said, the UN's security body can "dissolve" and reform entirely.

"If there is no alternative and no option, then the next option would be dissolve yourself altogether," Zelenskyy said.

Zelenskyy spoke to the council days after hundreds of Ukrainian civilians were found killed in Bucha after Russian forces retreated from the Kyiv region. Many corpses were found in partially excavated mass graves while others were found lying in the streets, according to media reports.

Zelenskyy used his speech on Tuesday to call for a reform of the world's security system.

In order to help guarantee peace moving forward, Zelenskyy said, "We must do everything in our power to pass on to the next generation an effective UN with the ability to respond preventively to security challenges."
