Ukraine’s President Volodymyr Zelensky has accused Russia of preparing to blow up a dam at a hydroelectric plant in southern Ukraine, which would lead to a “large-scale disaster”.
In his overnight address he said the Kakhovka dam on the Dnieper river had been mined by Russian forces, according to Ukrainian information.
The dam is under Russian occupation, but Ukrainian forces are closing in.
Russia has already accused Ukraine of firing missiles at the Kakhovka dam.
The dam also provides Russia with one of the few remaining routes across the Dnieper river in the partially occupied Kherson region.
Russian-installed authorities in Kherson have rejected Ukraine’s allegations of a plot to destroy the structure. They blamed Ukrainian forces for an attack on another key crossing, the Antonivskiy Bridge. Four people were killed, including the head of a TV channel, officials said.
