Russia claims Ukraine now developing nuclear arms with US help

Russia is blaming Ukraine for developing nuclear capabilities in cooperation with the US, adding to its previous claims of its neighbor developing biological weapons in US-backed research labs in Ukraine.

The claims weren't backed by any evidence or an explanation on how the besieged country could suddenly start developing functioning nuclear arms.

"The creation of nuclear weapons by Ukraine would threaten the security of the whole world and provoke the outbreak of a nuclear war; Russia could not allow uncontrolled Ukrainian nationalists to have them," Russian Federation Security Council Secretary Nikolai Patrushev said.
