Ukraine said on Wednesday there was a danger of a radiation leak at the Chernobyl nuclear power station after electricity was cut off to the plant, but the U.N. nuclear watchdog saw "no critical impact on security".
State-run nuclear company Energoatom said a high-voltage power line had been damaged during fighting between Ukrainian troops and Russian forces who are occupying the defunct plant, and that it had been cut off from the national power grid.
