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.

Ukrainian Defense Forces targeted and destroyed Russian arsenals in the Tver and Krasnodar regions of the Russian Federation early Saturday morning.

A recent poll found that 49 percent of people would back withdrawing without achieving the Kremlin's military objectives.
