A Russian attack drone slammed into a spent nuclear fuel storage facility within the Chernobyl exclusion zone in the early hours of Sunday, Ukrainian officials said, partially destroying a reception building and igniting a blaze that was quickly extinguished. No spent fuel was present in the stricken structure at the time of the strike, and radiation levels remained within normal limits, according to Ukraine’s state nuclear agency Energoatom. President Volodymyr Zelensky denounced the operation as a “deliberate” and “extremely vile Russian strike”, while the International Atomic Energy Agency (IAEA) confirmed it had been notified and would soon dispatch an inspection team.

The attack, which Kyiv said was carried out with a Shahed-type drone, struck the Centralised Spent Fuel Storage Facility, roughly 15 kilometres from the decommissioned Chernobyl power plant, site of the 1986 disaster. The impact, at around 2.10 a.m. local time, caused a fire covering some 40 square metres and shockwave damage to adjacent structures. Though no injuries were reported, the incident revived memories of repeated Russian strikes on the Zaporizhzhia atomic power plant in the south, where fighting has frequently endangered nuclear safety.

Viewed from European capitals, the strike injected fresh urgency into diplomatic efforts. Zelensky was expected to meet British Prime Minister Keir Starmer, French President Emmanuel Macron and German Chancellor Friedrich Merz in London later on Sunday to discuss Western support, ensuring the Chernobyl incident would dominate the agenda. French officials privately termed the attack “reckless”, while London reiterated that targeting nuclear infrastructure violates international norms. Moscow, however, remained silent, offering no public comment on the allegations.

The IAEA, which has maintained a monitoring mission at Chernobyl since Russian forces briefly occupied the site in 2022, said the building’s contents—large quantities of nuclear material stored metres away—were not affected. The UN watchdog has long warned that militarising nuclear sites risks a catastrophic accident. Meanwhile, a separate Russian drone attack on the same day killed three civilians at a bus stop in the Zaporizhzhia region, underscoring the relentless bombardments far from the front lines.

Analysts note that deliberately targeting a disused nuclear facility, even one temporarily empty of fuel, represents an escalation in psychological warfare designed to unnerve Ukraine and its allies. With the IAEA team set to visit the site promptly, the international community will be watching for any sign of radiological release. As the war grinds into its fifth year, such incidents test the limits of diplomatic deterrence and reinforce calls for tougher security guarantees around critical infrastructure.
