Ukrainian drones operated by military intelligence (HUR) attacked an oil refinery in the Russian city of Saratov on Nov. 8, a military intelligence source confirmed to the Kyiv Independent.
Earlier in the day, Saratov Oblast Governor Ruslan Busargin said that a Ukrainian drone targeted the city.
According to Busargin, air defenses downed the drone over the city and debris fell in the industrial area in the Zavodsky district. He did not report any casualties or damage.
The city hosts the Saratov Oil Refinery, formerly known as the Cracking Plant, which is part of Rosneft, the state-run oil company. The refinery is located in the city's Zavodsky District.
The HUR source said drones hit one of the plant's oil refineries and fuel oil tanks, and cited local media reports of multiple explosions.
Overnight, a total of 17 Ukrainian drones were "destroyed and intercepted," according to a report by the Russian Defense Ministry. Six drones were reportedly shot down over Saratov Oblast.
Saratov is a city in southwestern Russia, located nearly 1,500 kilometers (932 miles) from the border with Ukraine.
This is not the first time drones have attacked Saratov Oblast — drones reportedly struck Saratov Oblast overnight on Aug. 26. At least four civilians were reportedly injured in the attack.
