Ukraine's Chernobyl nuclear power plant has been cut off from electricity supplies.
Power lines were damaged by shelling, according to Ukrainian grid operator Ukrenerho and fighting north of Kiev is currently preventing any repair work.
According to the agency, 210 technicians and local safety staff have been on duty continuously for almost two weeks as there has been no shift change since Russian forces took control of the facility almost two weeks ago.
They have water and food, but their situation is deteriorating. In addition, the IAEA has lost contact with its monitoring equipment, which ensures that all nuclear material is in place.
Elsewhere in Ukraine another nuclear power plant and some other facilities with stocks of nuclear material have also been affected by the Russian invasion. However, no leakage of radioactive material has so far occurred.
