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.

Competing claims have emerged over a deadly attack on a boarding school in Sudzha, a city in Russia’s Kursk region that has been under Ukrainian control for five months.

Russia launched a barrage of drones and missiles on Ukraine on Saturday, killing at least four civilians and damaging residential buildings and infrastructure across the country, Ukrainian officials said.
