Vyacheslav Volodin claimed that the European Parliament calling for strikes inside Russia "leads to a world war using nuclear weapons".

Russian Foreign Minister Sergey Lavrov said that Russia possesses weapons "that will have serious implications for the handlers of the Ukrainian regime."

Ukraine's foreign minister said on Saturday that Russia is planning strikes on Ukrainian nuclear facilities before the winter, and urged the U.N.'s nuclear watchdog and Ukraine's allies to establish permanent monitoring missions at the country's nuclear plants.
