UN expresses concern over water shortage at Ukrainian nuclear plant after dam collapse.

The UN atomic watchdog has expressed concern over a "significant discrepancy" in water level data at the breached Kakhovka dam used for cooling the Zaporizhzhia nuclear plant's reactors. The International Atomic Energy Agency has requested wider access to the area to investigate the issue. The water from the reservoir is used to cool the facility's six reactors and spent fuel storage. The Kakhovka hydropower dam's destruction has flooded towns downstream and forced thousands of people from their homes.
