Ukrainian drones operated by military intelligence (HUR) attacked the Zenit oil depot in Russia's Kirov Oblast on Aug. 28, a HUR source confirmed for the Kyiv Independent.
The attack caused a fire at two oil tanks, the source said, confirming that this is the first drone attack on a Russian facility in Kirov Oblast.
According to Kirov Oblast Governor Alexander Sokolov, Russian air defenses shot down two drones while three others "fell" and started a fire near the Zenit oil facility in the town of Kotelnich. No casualties or damages were reported.
"The target is located more than 1,200 kilometers (745 miles) away from Ukraine's border. The Zenit oil depot is a facility of the enemy military-industrial complex and provides fuel to the Russian occupation forces," the source said.
The Kyiv Independent could not verify these claims.
Russia's Defense Ministry claimed that air defense also shot down eight drones over Voronezh Oblast and four over Rostov Oblast overnight.
Earlier in the day, a HUR source confirmed to the Kyiv Independent that Ukrainian drones operated by the military intelligence and the Special Operation Forces hit an oil depot in Rostov Oblast, setting it on fire.
The BBC's Russian service reported on Aug. 28 that drones have attacked oil refineries and infrastructure sites in Russia and on Russian-occupied territories, including Crimea, at least 64 times this year.
