EXPLAINER: Power cuts raise risk at Ukraine nuclear plant

BERLIN (AP) — A Ukrainian nuclear power plant that has been surrounded by Russian forces lost power Wednesday morning when a Russian missile damaged a distant electrical substation, increasing the risk of radiation disaster, according to the plant's operator.
