A Russian missile attack killed at least four people and damaged an educational facility in the city of Kryvyi Rih in southern-central Ukraine on Friday, the regional governor said.
At least five others were hurt, and three of them were in a serious condition in hospital, Serhiy Lysak, the governor of the Dnipropetrovsk region, said on Telegram.
Two five-story buildings were damaged and one caught fire, he said.
Several explosions reverberated through the city, witnesses said on social media, after Ukraine's air force warned of the threat of a ballistic missile attack from Russia-occupied Crimea.
Russia, which began it's full-scale invasion of Ukraine almost three years ago, did not immediately comment on the reports from Kryvyi Rih, the hometown of Ukrainian President Volodymyr Zelenskyy.
