Russian authorities at the Zaporizhzhia nuclear power plant reported that a projectile struck an internal gallery on Sunday, narrowly missing one of the reactors.
The administration, installed by Moscow, stated that the impact did not damage the reactor compartment or cause any radioactive leakage.
Kyiv has not yet confirmed responsibility for the specific strike at the nuclear facility, though Ukrainian forces have acknowledged ongoing operations against strategic Russian infrastructure.
The incident marks a significant escalation in the targeting of critical energy assets.
In recent weeks, Ukrainian forces have demonstrated the ability to strike deep into Russian territory, hitting one of the country's largest natural gas complexes near the Kazakhstan border and the Omsk refinery in Siberia, Russia's largest oil processing facility.
These strikes, located hundreds to thousands of kilometers from the front line, signal a shift in Ukraine's long-range strike capabilities and strategy.
