[United Nations: Cahovka Dam disaster may cause severe Water shortage for more than 700000 people]-Abreu, spokesman for the Office for the Coordination of Humanitarian Affairs of the United Nations in Ukraine, said: "according to our calculations, in the Dneboro region, for example, 200000 people have been cut off from their homes." He warned that more than 700000 people would be affected because not only in the Herzon region, the reservoir is the only source of water in southern Ukraine. In the major cities of the Dniepro region, centralized water supply has been completely cut off in some places, while the availability of water resources in others is extremely limited.
