Russia and Ukraine exchanged a massive wave of drone and missile strikes overnight that pummeled the industrial and commercial infrastructure of both countries, resulting in several casualties and intensifying the four-year war.

Ukraine launched more than 800 drones in its largest aerial attack on Russia, killing five people in the residential area of the southern Rostov region. Two more people were killed in the Belgorod and Moscow regions.

Russia’s defence ministry said it had intercepted 822 drones across the country overnight, with Moscow regional governor Andrey Vorobyov describing the assault as “one of the most massive drone attacks in recent memory.”

Images showed that the Wildberries site, Russia’s largest online retailer that Ukraine calls “Russian Amazon”, in Podolsk was completely destroyed in Kyiv’s assault. Since mid-July, Ukraine has struck around 20 warehouses and buildings linked to the company, which it accuses of supplying components for Russian drones.

The attacks come after Ukraine ⁠used Flamingo missiles to strike a Russian rocket and ⁠space centre ⁠in ⁠Samara that it says supports Russia’s ⁠nascent Starlink-style satellite internet network, according to Ukrainian President Volodymyr Zelenskyy.
