Around 210 technicians and locally employed security guards have been working at the decommissioned nuclear power plant for almost two weeks without stopping because it has not been possible to send in new shifts after Russia seized control of the plant.
They have food and water, but their situation is deteriorating, according to the IAEA.
In addition, the IAEA no longer has contact with monitoring equipment in the facility. Such equipment enables the IAEA to know that all nuclear material is in place.
