Russian missiles struck a children’s hospital in Kyiv and killed at least three people elsewhere in the Ukrainian capital Monday, authorities said, while another attack in the central Ukrainian city of Kryvyi Rih killed at least 10 people.

It was the biggest bombardment of Kyiv in several months. The daylight attacks included Kinzhal hypersonic missiles, one of the most advanced Russian weapons, the Ukrainian air force said. The Kinzhal flies at 10 times the speed of sound, making it hard to intercept. City buildings shook from the blasts.
