WASHINGTON (AP) – The collapse of a major dam in southern Ukraine has increased global prices of wheat and corn, endangered crops in the country’s breadbasket and threatened drinking-water supplies. Both sides in the war are rushing to evacuate residents and blaming each other for the destruction. Ukraine accused Russian forces of blowing up the Kakhovka dam and hydroelectric-power station on the Dnieper River in an area that Moscow controls, while Russian officials blamed Ukrainian military strikes in the contested area. It was not possible to verify the claims. The disaster has potentially far-reaching environmental and social consequences as homes, streets and businesses flooded downstream and emergency crews began evacuations.
