Russia denied targeting the hospital, saying it had been hit by fragments of a Ukrainian air defence missile, while Ukraine said it had found remnants of a Russian cruise missile. Lesia Lysytsia, a doctor at the hospital, told the BBC the moment the missile struck had been "like in a film" with a "big light, then an awful sound". "One part of the hospital was destroyed and there was a fire in another. It's really very damaged - maybe 60-70% of the hospital," she said. Pictures from the scene showed young children - some with IV drips - sitting outside the hospital as it was evacuated. Vitaliy Klitschko, Kyiv's mayor, said the two who died at the hospital were adults - one of whom was a doctor. He added that rescuers feared more people were trapped under the rubble. Ohmatdyt is a major hospital which carries out cancer treatment and organ transplants.
