"Today it was reported that out of seven people who were grazing cattle, five drowned. Now we are evacuating the remaining two," Leontiev told the Soloviev Live show.
The official added that 41 people have received injuries and were hospitalized.
The upper part of the Kakhovka HPP was destroyed overnight on Monday into Tuesday. The Novaya Kakhovka city authorities later confirmed that the dam was destroyed only partially, but it caused an uncontrollable outflow of water to towns downstream.
Moscow and Kiev blamed each other for the incident. Authorities in some of the affected areas have started evacuating the population.
Commenting on the incident, Russian Ambassador to the United Nations Vassily Nebenzya stated that Moscow regrets that the international community did not hear its warnings last October about the potential threat that the destruction of the Kakhovka hydroelectric power plant and dam would pose.
The UN envoy emphasized that statements blaming Russia for the incident use the same flawed logic as claims that Moscow played a role in the Nord Stream destruction. Nebenzya criticized the behavior of the UN Secretariat for its 'politicized' statements and for not condemning Kiev over the attack.
The Novaya Kakhovka dam is the sixth and last stage of the cascade of Dnipro hydroelectric power plants located 5 kilometers from the city of Nova Kakhovka in the Kherson Region, which became part of Russia following a referendum in September 2022.
