Safety at the Russian-held Zaporizhzhia nuclear power plant (ZNPP) in Ukraine is worsening daily, Ukraine’s energy minister said on Friday, pledging to keep pressuring Russia at the U.N. nuclear watchdog to withdraw from the site.

The International Atomic Energy Agency’s 35-nation Board of Governors passed a resolution late on Thursday condemning Russia’s occupation of Europe’s biggest nuclear power plant and expressing “grave concern” at lack of staffing and maintenance two years after its capture.

“The general situation is moving to (a) nuclear accident and it’s very important to stop immediately this (Russian) presence,” Ukrainian Energy Minister German Galushchenko told a news conference.

“The number of problems (has) only increased each day, each day. And (in) one more month, we would have another problem. Another month, we will have some additional problems,” he said, adding that Ukraine would keep pushing for more resolutions.
