In brief
A drone strike tore a hole in the wall of a turbine hall at reactor six of the Zaporizhzhia Nuclear Power Plant, with no radiation leak detected.
IAEA chief Rafael Grossi called the incident a grave threat to nuclear safety and said on-site experts have requested access to the damaged building.
Russia's Rosatom accused Ukraine of a deliberate, fiber-optic-guided drone attack, while Kyiv dismissed the claim as a 'propaganda trick' and 'nuclear blackmail'.
The incident was part of a wider exchange of drone attacks, with Russia reporting strikes on its oil infrastructure and Ukraine reporting a fire at a courier depot in Dnipro.
Russian authorities on the occupied Crimean Peninsula limited gasoline sales to 20 liters per person per day due to a fuel shortage, causing queues at stations.

The Incident
A drone struck the turbine hall of reactor six at the Zaporizhzhia Nuclear Power Plant in southern Ukraine on Saturday, tearing a hole in the building's wall. The International Atomic Energy Agency (IAEA), which has a team stationed at the Russian-occupied facility, confirmed the damage and reported that no increase in radiation levels had been measured. The IAEA stated this was the first drone attack on the plant's grounds since April 2024.
“Attacking a nuclear facility is like playing with fire.”
Blame Game
Russia's state nuclear corporation, Rosatom, and its head, Alexei Likhachev, accused Ukraine of a deliberate attack, claiming the drone was guided by a fiber-optic cable, which ruled out an accidental strike. The Ukrainian military and foreign ministry vehemently denied the accusations, calling them a "propaganda trick" and an attempt at "nuclear blackmail." Kyiv argued it would be illogical to attack a facility on its own territory that it intends to regain control of.
“It is incomprehensible why Ukraine would attack a plant on its own territory that it wants to bring back under its control.”
IAEA Response
IAEA Director General Rafael Grossi expressed serious concern, calling the incident a grave one that endangers the fundamental principles of nuclear safety. IAEA experts on site have requested access to the affected building to conduct a full assessment. The agency reiterated its call for an immediate halt to all attacks on or from the plant to prevent a nuclear accident.
Broader Escalation
The incident occurred amid a flurry of reported drone strikes deep inside both countries. Russia reported that Ukrainian drones attacked industrial and energy facilities in several regions, including Kirov, over 1,300 kilometers from Ukrainian-controlled territory. Fires were reported at an oil depot in Armavir, Krasnodar region, and a tanker and port in Taganrog on the Sea of Azov were hit, injuring two people. In Ukraine, a Russian drone strike set ablaze a branch of the Nova Poshta courier company in Dnipro, prompting President Volodymyr Zelenskyy to call for more air defense support.
“These attacks must stop.”
Fuel Crisis in Crimea
On the occupied Crimean Peninsula, a fuel shortage led to the rationing of AI-95 gasoline to 20 liters per person per day, starting Saturday. Local media reported long queues at gas stations, and the sale of fuel coupons to individual customers was suspended. The Russian-installed governor of Sevastopol, Mikhail Razvozhaev, stated that fuel supplies would be increased and that emergency services had sufficient reserves.
Plant Status
Zaporizhzhia, Europe's largest nuclear power plant with six reactors and a nominal capacity of 6,000 megawatts, has been under Russian control since March 2022. All reactors are shut down, but the plant still requires external electricity for its cooling and safety systems. The Dnipro River, which separates Russian and Ukrainian forces, runs nearby.
