Ukrainian drones struck two more warehouses used by the online retailer Wildberries, as well as a third in the Moscow region that killed five people as Russia and Ukraine continued exchanging cross-border strikes with US-mediated peace talks stalled.Kyiv has been seeking to disrupt the operations of Wildberries, the Russian equivalent to Amazon, in recent weeks, claiming it is aiding the war against Ukraine by supplying goods that have military purposes.Early on August 4, Wildberries' warehouses in the Tver and St Petersburg region were hit as Ukraine tries to bring the war, now in its fifth year, to ordinary Russians to put pressure on the Kremlin to renew peace talks.A third warehouse in the Moscow region was also hit, leaving five dead and at least 10 others injured, according to Moscow region Governor Andrei Vorobyov."Several fires broke out in the industrial zone of Novoselki as a result of a drone strike. The largest was at a warehouse, where the open flames have already been extinguished," Vorobyov said.According to media reports and Telegram channel ASTRA's OSINT analysis, Ukrainian drones also struck the Syzran oil refinery in Russia's Samara region, with geolocated footage showing black smoke rising from the facility.The Rosneft-owned refinery processes 8.5 million tons of crude oil annually, accounting for more than 3 percent of Russia's total refining capacity.In recent weeks, Ukrainian forces have struck more than a dozen warehouses belonging to Wildberries across multiple Russian regions.The retailer has called the attacks, which have hit around 15 different company facilities, "acts of terrorism."
