Ukraine's state-run nuclear power operator Energoatom said a Russian cruise missile few "critically low" on Sunday morning over a major nuclear power plant.
"It's probable that was the missile that was fired in the direction of Kyiv," the operator of the Pivdennoukrainska plant, also called the South Ukraine Nuclear Plant, said in a post on the Telegram messaging app.
Reuters could not immediately verify the claim.
Early on Sunday, several explosions rocked Kyiv
Pivdennoukrainska is Ukraine's second largest nuclear plant located near in the Mykolaiv region, about 350 km (220 miles) south of Kyiv.
