Putin Threatened Retaliation if Nuclear Weapons Transferred to Ukraine

"What do you think, at the level of common sense? If the country with which we are essentially fighting now becomes a nuclear power, what should we do? In this case, we will take and use all, I want to emphasize this, exactly all the means of defeat available to Russia - everything. We will not allow this. We will watch their every move," Putin told reporters when asked about Russia's reaction to the possible transfer of nuclear weapons to Kiev.

The Russian head of state arrived in Astana on Wednesday for a two-day state visit at the invitation of Kazakh President Kassym-Jomart Tokayev.
