Ukrainian FP-1 drones struck an Ozon warehouse in Chapayevsk, Russia’s Samara Oblast, overnight on 22 August 2026, manufacturer Fire Point said.

The attack on the Chapayevsk facility expands Ukraine’s warehouse campaign from Wildberries, Russia’s largest online marketplace, to its second-largest rival, Ozon. Ukraine has repeatedly targeted Russia's major e-commerce distribution hubs to disrupt commercial logistics that Kyiv says help sustain Moscow’s war.

Ozon said the attack injured people and prompted the evacuation of more than 500 employees.

The strike was the first confirmed Ukrainian attack to damage and set fire to an Ozon warehouse, Reuters reported. A drone alert forced Ozon to evacuate a facility in Tatarstan on 31 July, but the building was undamaged and later reopened.

Fire Point said the facility is one of Ozon’s largest warehouses in Volga Oblast, storing goods and processing more than 215,000 orders for delivery each day.

Ozon and Wildberries—Russia’s two largest online marketplaces—and their smaller rivals collectively sell goods and services worth the equivalent of 8.5% of Russia’s GDP and employ 4 million people, Reuters reported in July.

Ozon suspended operations indefinitely and stopped accepting seller deliveries, the company said. As a result, shipments are being redirected to other facilities, while affected orders will either be fulfilled elsewhere or canceled and refunded.

Several people were receiving medical treatment, Samara Oblast Governor Vyacheslav Fedorishchev claimed. Neither he nor Ozon specified how many people were injured, and the extent of the damage remains unclear.

Ukraine’s previous strikes on Russian warehouses

Ukrainian drones had previously concentrated on Wildberries, Russia’s largest online retailer. Since 18 July, Ukraine has struck at least two dozen Wildberries warehouses, Reuters reported.

Ukrainian officials have alleged that Wildberries warehouses move military-linked goods, including drone components. The Kremlin has denied that the company supplies Russian forces. Fire Point made no corresponding claim about the Ozon warehouse.

Ukraine’s military said the same overnight wave also hit the Novokuibyshevsk refinery in Samara Oblast and caused a fire.

Russian and occupation officials claimed that the broader wave caused civilian deaths and injuries in Yeysk, Belgorod, Bryansk, and Russian-occupied Luhansk.

Ukrainian forces struck production facilities at the Novokuybyshevsk oil refinery in Russia’s Samara Oblast overnight on 22 August, sparking a fire at the Rosneft-owned plant, Ukraine’s General Staff said. The extent of the damage remains under assessment.

Ukraine has repeatedly targeted Russia’s oil refineries to restrict military fuel supplies and reduce the energy revenues supporting Moscow’s war. The latest strike came as gasoline rationing returned to Moscow and St. Petersburg, and Rosneft capped nationwide purchases. Militarnyi described the plant as one of Russia’s 10 largest refineries.

The Rosneft-owned refinery can process about 8.8 million metric tons of crude annually and produces more than 20 petroleum products, including aviation fuel and diesel, Ukraine’s General Staff said.

Fire Point said FP-1 long-range drones were used to strike the refinery.

The same overnight wave also hit an Ozon logistics center in Chapayevsk, where people were injured, and work was halted, Reuters reported, citing the company.

Neither the damage to the refinery nor any interruption to production has been independently confirmed.

Ukraine keeps pressure on Russian fuel supplies

The strike came one day after Ukraine confirmed hitting Lukoil’s Perm refinery, approximately 1,530 kilometers from Ukraine’s northern border. That attack also caused a fire, according to the General Staff.

At least four Russian refineries went offline during August amid continuing Ukrainian attacks.

By mid-August, filling stations in at least 12 Russian regions were experiencing hours-long lines. Some areas had reintroduced purchase limits or rationing based on license-plate numbers, according to the same report.

Gasoline limits had also been reinstated in Moscow and St. Petersburg, while Rosneft had capped sales at 30 liters per vehicle across its nationwide filling-station network. Diesel purchases remained unrestricted.
