"The reservoir that forms the dam is a lifeline for the region and a critical source of water for millions of people," RIA Novosti quoted him as saying at a meeting of the UN Security Council.
Griffiths stressed that the damage from the destruction of the dam will make people's lives "unbearably harder", and the consequences of not being able to deliver water to millions of victims can be catastrophic.
In addition, according to the UN Deputy Secretary-General, the destruction of the hydroelectric power station threatens the movement of mines to the regions cleared of them.
Earlier, Russian Permanent Representative to the UN Vasily Nebenzya called on UN Secretary General António Guterres to condemn the undermining of the Kakhovka dam by the Kyiv regime.
According to him, this has already led to an environmental disaster - dozens of settlements are flooded, the Kakhovka reservoir and the North Crimean Canal, which supplies water to Crimea, are becoming shallow.
