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 under Ukrainian control.

Sergey Efremov, the deputy governor of Russia’s eastern region of Primorsky Krai, was killed after he returned to the Russian frontline from a battle with Ukrainian forces in the Kursk region. He was reportedly travelling in a car blown up by a landmine along with another Russian army officer.
