International Atomic Energy Agency (IAEA) chief Rafael Grossi announced on Wednesday that the Zaporizhzhia power plant was disconnected from the last backup external power line on Tuesday.
According to him, the plant is currently receiving power from the only working line left.
"The extremely vulnerable off-site power situation continues to pose significant safety and security challenges for this major nuclear facility. Even though the main power line remains in operation, the lack of backup power demonstrates that the nuclear safety and security situation at the plant remains precarious," he underlined.
