LONDON (Reuters) - The breach of a huge dam on the front-line Dnipro river has muddied the picture for a much-awaited Ukrainian counteroffensive against Russian invaders and threatens an environmental disaster for civilians living in the war zone.
Kyiv and Moscow have blamed each other for the collapse of the Nova Kakhovka dam in southern Ukraine that sent floods gushing towards surrounding towns and farmland and forced hundreds of civilians to flee on Tuesday.
