Ukraine on Sunday launched one of its largest aerial attacks on Russia since the start of the war, firing hundreds of drones and killing at least six people.

This attack occurred as Ukrainian forces increasingly take the war into the very heart of Russia nearly four and a half years into the full-blown conflict sparked by Moscow’s invasion.

Russia’s Ministry of Defense said it destroyed 822 Ukrainian drones overnight, as some 600 drones were detected heading toward Moscow. A third of the drones were destroyed over the Russian capital region.

Five people were killed in a drone strike in Russia’s southwestern Rostov region, as more than 150 drones damaged homes, hit a railway station and sparked a forest fire, according to local Governor Yury Slyusar.

An 83-year-old man was killed after a Ukrainian drone hit a private home in the Moscow region, local Governor Andrey Vorobyov said.

He also confirmed a separate attack had sparked a blaze at a warehouse owned by the Russian online retail giant Wildberries in the town of Podolsk.
