Ukrainian military commander Roman Kostenko has issued a warning that Russia may be preparing to deploy tactical nuclear weapons in the ongoing conflict. He believes that if Russia perceives it is losing, it could resort to using nuclear arms with yields ranging from several to dozens of kilotons. The potential targets include military bases, troop concentrations, and large cities. Kostenko has proposed legislation to create a distinct strategy for biological, chemical, and nuclear security to enhance national preparedness. This warning follows recent Ukrainian military actions, including a strike on Transneft's oil facility in Perm, which the Ukraine Security Service confirmed resulted in significant damage. The Russian government has reacted angrily, labeling the strikes as terrorist attacks. The situation has escalated tensions, with implications for regional and global security.
