A Russian ballistic missile killed four and wounded dozens as it hit a hotel in the central Ukrainian city of Kryvyi Rih late Wednesday, underscoring the danger posed by pointed strikes with insufficient air-defense cover.

More than 30 people were injured, almost half of whom are in a serious condition with doctors fighting for their survival, Mayor Oleksandr Vilkul said Thursday on Telegram. One of the patients died early Thursday, adding to the death toll.
