Russian reports say Ukrainian drones have struck a Russian arms depot deep inside the country, triggering explosions and the closure of a major highway.

A drone strike in Russia's southern Krasnodar region prompted evacuations after it sparked a fire. Meanwhile, three people were killed in a Russian missile attack on the Ukrainian city of Kryvyi Rih.

Russia said it was working to repel a Ukrainian drone attack on Toropets, where there's a major military depot, as explosions lit up the night.
