Ukrainian drones hit an oil refinery, a warehouse, and other sites in Russia's Volgograd region overnight. Russia and Ukraine also traded separate strikes elsewhere. Those strikes killed two people and injured nine others, according to Ukrainian and Russian officials.
Ukraine's General Staff announced on Telegram that its forces struck the Lukoil-Volgogradneftepererabotka refinery overnight. The strike started a fire at the site, the General Staff said.
Officials are still assessing the damage.
The refinery processes about 15 million tons of oil a year. It supplies gasoline, diesel and aviation fuel. That includes fuel for Russia's armed forces, the General Staff said.
Ukraine's Security Service, known as the SBU, wrote on Telegram that it also hit the refinery. It carried out the strike jointly with Ukraine's Defense Forces. The SBU called the plant one of Russia's largest oil refineries. It said the goal was to reduce Russia's military and economic power.
A fire also broke out at a logistics center run by Wildberries, Russia's online retail giant, in Volgograd. The company confirmed the attack on Telegram.
"A fire broke out at the company's logistics facility in Volgograd following an attack," Wildberries said in a statement, adding, "There are no preliminary reports of casualties. Logistics chains have been reorganized, and deliveries and order shipments are being handled at other facilities."
The company said fire crews reached the scene.
Kyiv accuses Wildberries of storing drone parts and helping the Russian military.
Ukraine first hit Wildberries warehouses on July 18-19. Those strikes hit Russia's Tambov and Moscow regions. They caused eight casualties and destroyed facilities.
The strike brings the reported total to 14 Wildberries logistics centers hit over the past two weeks.
On Thursday, Wildberries said a drone strike hit a warehouse in the Penza region. That strike sparked a fire, injured one person and forced the evacuation of more than 200 workers.
A Ukrainian drone also hit a separate Wildberries warehouse in Sarapul. That city sits about 1,100 kilometers east of Moscow.
The SBU said its joint operation also hit an aircraft plant in Russian-occupied Yevpatoria, in Crimea. Forces struck two aircraft hangars and a production workshop at the plant, the SBU said.
Forces also struck port infrastructure at Taman, the SBU said. It added that a large fire broke out there.
Ukraine's General Staff said its forces hit three more sites. Those include a Pole-21 electronic warfare complex near Holubivka. Forces also hit an ammunition depot near Naumivka in Crimea. A Russian command post near Bakhmut was the third target. The General Staff said damage checks for those sites continue.
Volgograd region Gov. Andrey Bocharov announced on Telegram that a Ukrainian drone strike injured five people. He said the strike sparked fires at a fuel and energy facility in southern Volgograd. It also hit warehouses in the city's Dzerzhinsky district. Bocharov said the strikes damaged civilian infrastructure.
"Emergency services are currently on the scene, and firefighting efforts are ongoing," Bocharov wrote.
Separately, Rostov region Gov. Yury Slyusar announced on Telegram that a drone strike injured one person in the city of Gukovo. He said the drone hit an apartment building. The strike caused floor slabs to collapse and forced residents to evacuate.
In Ukraine, a Russian attack killed two people and injured three others in the Nikopol district. Oleksandr Hanzha, head of the Dnipropetrovsk regional military administration, reported the toll.
Russia's Defense Ministry claimed it intercepted and destroyed 371 Ukrainian drones overnight. It said the drones targeted Russia, annexed Crimea, and the Black and Azov seas. Ukraine's Air Force made a separate claim. It said its forces shot down 195 Russian drones over northern, southern and eastern Ukraine.
Neither figure has independent confirmation.
