A Russian strike on a residential building in central Ukraine killed at least 14 people, including two children, emergency services said, one of many attacks across the country this weekend.

Russia launched a barrage of drones and missiles on Ukraine on Saturday, killing eight people and damaging dozens of residential buildings as well as energy infrastructure across the country, Ukrainian officials said.

The Ukrainian army said four people were killed and dozens - many of them elderly - were injured in the town of Sudzha in the Kursk region, which has been under Ukrainian control for five months. More than 80 people are reported to have been rescued from the building.
