Competing claims have emerged over a deadly attack on a boarding school in Sudzha, a city in Russia's Kursk region under Ukrainian control.

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.

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.

"At the time of the attack, dozens of local residents were inside the building preparing to evacuate," Ukraine's military said on Feb. 1, adding that nearly 95 people could be trapped under the rubble.

Kyiv and Moscow traded blame on Sunday for a strike on a school in a Ukrainian-occupied town in Russia's Kursk region, while Kyiv said new missile and drone attacks killed at least 18 people in Ukraine.
