(Reuters) - A Ukrainian drone attack killed one civilian in the Russian region of Belgorod bordering Ukraine, the regional governor said on Sunday. "A man was killed," Governor Vyacheslav Gladkov said of the overnight strike in a post on the Telegram messaging app. "He died from his injuries before the ambulance crew arrived."

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.

Ukraine's military said on Saturday that Russian forces had struck a boarding school housing people preparing for evacuation in a part of Russia's Kursk region held by Ukrainian forces, killing at least four people.
