Kyiv won't negotiate with Moscow after 'referendums', Zelensky tells UN

"In front of the eyes of the whole world, Russia is conducting an outright farce called a 'referendum' on the occupied territory of Ukraine," President Volodymyr Zelensky told the United Nations General Assembly.

Kyiv will not be able to negotiate with Russia after Moscow held annexation "referendums" in four occupied Ukrainian regions, President Volodymyr Zelensky told the United Nations General Assembly on Tuesday.

Ukrainian President Zelensky joined the meeting via video and reiterated his request for the changes to the Security Council that he made during the General Assembly last week and called for the expulsion of Russia from the Council. (AFP)

"Russia's recognition of the pseudo-referendums as 'normal', implementation of the so-called Crimean scenario, and yet another attempt to annex Ukrainian territory means that there is nothing to talk about with (the) current Russian president," he said in a video message at a meeting of the UN security council.

"In front of the eyes of the whole world, Russia is conducting an outright farce called a 'referendum' on the occupied territory of Ukraine," he said.

"People are forced to fill out some papers for a TV picture under the muzzles of machine guns.

"The figures of the alleged results of the pseudo-referendum were drawn in advance," he said.

Zelensky added that "threats to use nuclear weapons have become a constant narrative of Russian officials and propagandists".
