The Ukrainian atomic energy agency accused Russia on Monday of flouting nuclear safety by sending a "kamikaze" drone over part of the South Ukraine Nuclear Power Plant in the Mykolaiv region just after midnight.
Energoatom said the Iranian-made Shahed drone had been detected at 00:46 early Monday over the station and said it was calling on the international nuclear community to protect atomic sites from the risks of war.
"This is an absolutely unacceptable violation of nuclear and radiation safety," Energoatom wrote on the Telegram messaging app.
