Shoigu said that Russia is aware of Ukraine's attempts to create a "dirty bomb"

“We are aware of Kyiv’s attempts to create a “dirty” nuclear bomb, as well as its readiness to deploy NATO nuclear weapons on its territory,” Shoigu said.

He also recalled that Ukrainian President Volodymyr Zelensky recently called on Western countries to launch preventive nuclear strikes against Russia.

Earlier, Russia's first deputy representative to the UN, Dmitry Polyansky, said that Russia hopes that the West will prevent the provocation of Kyiv with a "dirty bomb" by the West.
