The Russian government on Sunday accused Ukraine of targeting its nuclear plant with drones that triggered a fire and caused damage to an auxiliary transformer.

The attack occurred on a day when Ukraine was celebrating its Independence Day.

According to reports, the drone targeted the Kursk Nuclear Power Plant, which is located close to the Ukrainian border.

Sharing details about the attack, the official press service of the plant wrote on Telegram: "On August 24 at 00:26 Moscow time, an unmanned combat aerial vehicle (UAV) of the Ukrainian Armed Forces was shot down by air defense near the Kursk NPP."

"The device detonated when it fell, damaging the transformer for its own needs," the statement said.

Fire crews extinguished the blaze.

"As a result, unit No. 3 was unloaded by 50%," the plant said.

No casualties have been reported in the attack.

"Currently, unit 3 is in operation at the Kursk NPP. Unit 4 is undergoing scheduled maintenance. Units 1 and 2 are in operation without generation. The radiation background at the industrial site of the Kursk NPP and the adjacent territory has not changed and corresponds to natural values," the plant said.

The International Atomic Energy Agency said it is currently monitoring the situation at the plant.

IAEA said: " IAEA monitoring confirms normal radiation levels near Kursk NPP; Russia says reactor unit’s power reduced due to auxiliary transformer damage but fire extinguished and no injuries."
