Ukrainian drones strike Saratov refinery, fires reported in Rostov and Oryol

Drones attacked Russia's Saratov region overnight, with a local oil refinery reportedly hit, according to regional governor Roman Busargin, who reported casualties and damage to civilian infrastructure. Telegram channels suggest the Saratov refinery, which processes about 7 million tons of oil annually producing gasoline, diesel, and other products, may have been struck. Separately, a fire near Rostov's Almaz defense plant and another in Oryol, possibly at the Proton factory, were reported. The attacks mark the latest in a series of Ukrainian drone strikes on Russian energy and military infrastructure, with Russian officials previously claiming a missile attack on the Proton facility.
