Ukraine strikes Russia’s second-largest oil refinery again in major overnight attack, also hitting airfield and drone launch site

Ukraine’s Defense Forces struck three Russian military and energy targets overnight on 29-30 August, including a major oil refinery in Leningrad Oblast, a site used to store and launch attack drones in Rostov Oblast, and an airfield in Krasnodar Krai, Ukraine’s General Staff said.
Ukraine has increasingly targeted energy and military infrastructure inside Russia as part of an effort to disrupt the resources supporting Moscow’s war effort. Russia’s military relies heavily on fuel and other petroleum products produced at major refineries, while oil exports provide revenue that helps fund the war.
The General Staff said the strikes caused fires at all three sites. The extent of the damage is still being assessed.
Ukraine strikes one of Russia’s largest oil refineries
In Kirishi, Leningrad Oblast, Ukrainian forces struck the Kirishi oil refinery, also known as KINEF, Russia’s 2nd largest oil refinery.
The refinery has an annual processing capacity of about 20 million metric tons of crude oil and produces motor fuels, aviation fuel, diesel and other petroleum products, according to the General Staff. It also supplies fuel for Russia’s military.
KINEF has been targeted repeatedly since Russia launched its full-scale invasion. The latest strike is at least the sixth reported Ukrainian attack on the refinery.

Russian authorities acknowledged damage in Kirishi following the overnight attack, according to Russian OSINT outlet ASTRA. Leningrad Oblast Governor Alexander Drozdenko claimed several residential buildings were damaged, with windows blown out in some apartments, while a fire broke out in the city’s industrial zone. He said the industrial fire and fires from drone debris had been extinguished.
ASTRA reported that videos from residents showed a large fire at what appeared to be the KINEF refinery. ASTRA also geolocated footage of an explosion at the upper floors of an apartment building in Kirishi, where residents reported hearing air defense activity. The footage has not been independently verified.
Drone launch site struck in Rostov Oblast
Ukrainian forces also struck a site in Millerovo, Rostov Oblast, used to store, prepare and launch attack drones.
The General Staff said a fire was reported at the facility following the strike.
Millerovo has been repeatedly used by Russian forces as a base for launching attacks against Ukraine. Striking drone infrastructure can disrupt the storage, preparation and deployment of the weapons used in Russia’s ongoing aerial campaign.

Fire reported at Yeysk airfield
A Ukrainian strike also hit Yeysk airfield in Russia’s Krasnodar Krai, according to the General Staff.
A fire was reported at the site after the strike. The General Staff did not provide details on which facilities or equipment at the airfield were damaged.
The three strikes were part of a broader Ukrainian campaign against Russian military infrastructure and the energy facilities supporting Russia’s war effort.
Russia’s Defense Ministry claimed that its air defenses intercepted or destroyed 494 fixed-wing drones overnight across Russia and occupied Ukrainian territory. It said the drones were detected over Leningrad, Bryansk, Belgorod, Kaluga, Kursk, Tver, Smolensk, Oryol, Pskov, Tula, Novgorod and Rostov oblasts, as well as Krasnodar Krai, Moscow, occupied Crimea and the Azov and Black seas.
The General Staff said operations against key Russian targets are continuing, while the extent of the damage from the overnight strikes is still being determined.
