The International Atomic Energy Agency (IAEA) reported that Ukraine informed it of a fire at the Dniprovska 750 kilovolt electrical substation caused by military activities. The fire resulted in the partial disconnection of the South Ukraine Nuclear Power Plant from its external power supplies. Firefighters were deployed to extinguish the blaze. The substation also provides external power to the Russian-controlled Zaporizhzhia Nuclear Power Plant. IAEA Director General Rafael Grossi expressed grave concern, stating that such substations critical to nuclear safety must never be targeted.
