Ukrainian drones struck across four Russian regions before dawn on 4 August, setting fires at a Rosneft oil refinery and targeting two logistics hubs of Russia's largest online retailer, Militarnyi reported. The raid reached Samara, Leningrad, Moscow, and Nizhny Novgorod oblasts, hitting both the fuel that powers Russia's military and the warehouses that Kyiv says supply its army. Russian regional officials confirmed damage while claiming air defenses repelled much of the attack.
Syzran refinery burns again
Ukrainian drones attacked the Syzran oil refinery in Samara Oblast overnight more than 800 km from the war zone in Ukraine, and Militarnyi geolocated the rising smoke to the plant. A drone-danger alert went up in the region after 1 a.m., and residents then reported explosions in the city before a column of smoke climbed over the refinery.
The plant belongs to Rosneft and processes more than 8.5 million tons of crude a year, more than 3% of Russia's national total. It turns out gasoline, diesel, aviation kerosene, and bitumen, and supplies fuel to Samara, Saratov, and Penza oblasts as well as parts of central Russia. It also feeds airfields and military units of Russia's Central and Southern military districts. The refinery sits more than 800 km from Ukraine's border.
Ukraine's Defense Forces have hit this refinery many times before. Drones struck it overnight on 11-12 July, starting a large fire that analysts assessed reached every primary crude-processing unit. Samara Oblast Governor Vyacheslav Fedorishchev said a fire from the attack in the region was being extinguished.
Astra says residents of Kstovo in Nizhny Novgorod Oblast reported a fire after the attack, though the struck object there stayed unclear. The city is home to a Lukoil oil refinery about 800 km from Ukraine.
Warehouses near St. Petersburg and Moscow
In the morning, Ukrainian drones hit a logistics compound near Krasny Bor in the Tosnensky district of Leningrad Oblast, roughly 820 km from Ukraine's northern border. Eyewitnesses filmed a heavy fire, and Wildberries confirmed a blaze at its facility there.
Its Krasny Bor site covers 154,000 square meters, one of the retailer's largest surviving logistics hubs in the region. Ukrainian drones burned two others in Leningrad Oblast on 24 July.
Leningrad Oblast Governor Alexander Drozdenko claimed air defenses downed 17 drones overnight and confirmed damage to the warehouse zone near Krasny Bor. An OSINT analyst at the Russian Telegram channel Astra, reviewing eyewitness video, placed the smoke over a site holding two complexes: the Wildberries hub and a Lenta depot of 70,000 square meters. The analyst said the damaged complex could belong to either.

Drones also struck Chekhov near Moscow, about 400 km from Ukraine, where Astra identified the likely target as a Wildberries warehouse. Moscow Oblast Governor Andrei Vorobyov confirmed the strike and claimed five people were killed and six injured.
Why the warehouses
President Volodymyr Zelenskyy has previously explained that Ukraine strikes what he calls "Russia's AliExpress" because the marketplace supplies occupying forces with sanctioned components for drones and navigation equipment. Ukraine's military command lists Wildberries among its long-range targets as a retailer that also moves non-lethal military gear.
Ukraine's Defense Forces began striking Wildberries logistics sites on 18 July. The company tightened rules on 3 August, allowing warehouse staff only button phones without cameras, after employees filmed the strikes and shared the footage.
