Ukraine has launched a barrage of drones on arms depots in Russia, in the second such attack this week. Russia's defence ministry said it intercepted 101 drones but multiple depots were set ablaze in the country's south and north-west.

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.

Ukraine struck the Moscow region on Tuesday in its biggest drone attack so far on the Russian capital, killing at least one woman, wrecking dozens of homes and forcing around 50 flights to be diverted from airports around Moscow.
