A fire broke out at the Kursk Nuclear Power Plant in Russia after Russian military forces shot down a Ukrainian drone flying near the plant, the press service of the plant said.
The drone -- one of several reported on August 23 by Russian authorities -- fell on an auxiliary transformer, sparking the fire, which has been extinguished. There were no injuries, according to the press service's statement.
"A combat unmanned aerial vehicle (UAV) belonging to the Armed Forces of Ukraine was shot down by air defense systems near the Kursk Nuclear Power Plant," the press service said in a statement on Telegram.
"Upon impact, the drone detonated, resulting in damage to an auxiliary transformer," the statement said.
As a result of the explosion, unit three of the plant was reduced to 50 percent capacity, the press service said.
Radiation levels at the site and in the surrounding area have not exceeded normal limits, it added.
There was no immediate comment from Ukraine. Kyiv has increased its drones strikes inside Russia over the past several months in response to Russia's continued attacks on Ukraine. It says the attacks are aimed at destroying infrastructure that is crucial to Moscow's military efforts.
