Ukrainian drones attacked Moscow and the surrounding area, as well as the Yaroslavl oil refinery, one of Russia's largest oil processing facilities, overnight on Aug. 28, Russian Telegram channels reported, citing eyewitnesses, Kyiv Independent reports.
Footage published by the Russian Telegram channel Supernova+ appears to show at least two separate fires burning on the plant's territory. OSINT analysts from Russian independent media outlet ASTRA geolocated the footage to Yaroslavl's Dyadkovo district and identified the facility as the Slavneft-YANOS refinery.
The latest attack marked the eighth on the Slavneft-YANOS refinery in 2026, which has been targeted repeatedly in previous Ukrainian attacks, including on Aug. 6, July 16, July 6, May 22, May 8, April 26, and March 28.
The Slavneft-YANOS refinery, located about 250 kilometers (150 miles) northeast of Moscow and roughly 700 kilometers (435 miles) from Ukraine's border, processes around 15 million tons of oil per year, making it one of Russia's five largest oil refineries.
The plant produces gasoline, diesel fuel, aviation kerosene, oils, bitumen, liquefied gases, and fuel oil. It is the main refining asset of Slavneft, which is jointly controlled by Russian state energy giants Rosneft and Gazprom.
