Ukraine's Security Service (SBU) confirmed that it, together with the country's defense forces, carried out a series of strikes on fuel-energy and military infrastructure facilities in Russia, including the Yaroslavl oil refinery and the Yaroslavl linear production-dispatch station, Deutsche Welle reported.
The SBU said the strikes also hit the oil terminal of the Vysotsk seaport in Leningrad Oblast, disabling two oil-loading stands and damaging three oil-product tanks. Drones also struck the Pervy Zavod refinery in Kaluga Oblast, where explosions sparked a fire.
Russia's Defense Ministry reported that overnight on July 6, air defense systems intercepted and destroyed 519 Ukrainian fixed-wing drones over 20 Russian regions, annexed Crimea, and the Sea of Azov. The ministry did not specify how many drones attacked the country in total, only reporting those shot down.
Yaroslavl Oblast Governor Mikhail Yevrayev said more than 70 drones were shot down approaching Yaroslavl, and two people were hospitalized with shrapnel wounds. Traffic on the exit from Yaroslavl toward Moscow was temporarily blocked. The outlet Astra published photos of smoke near the Slavneft-YANOS refinery. Yevrayev did not report consequences for the plant, but The Insider analyzed NASA FIRMS satellite monitoring data and found a thermal anomaly on the plant's territory near the flare system. The outlet noted the data does not allow determining the cause — the anomaly could be linked to a fire after the attack or to normal operation of the flare stack.
In Leningrad Oblast, Governor Alexander Drozdenko said more than 60 drones were shot down, and infrastructure facilities at the Luga training ground and near the ports of Ust-Luga and Vysotsk were damaged. No casualties were reported. Flights at Pulkovo Airport were temporarily restricted.
Annexed Crimea was left without electricity after an attack on energy infrastructure. Russia-appointed Sevastopol Governor Mikhail Razvozhayev said the city was completely blacked out, trolleybuses would not run in the morning, and social facilities switched to backup power. He later said power had been restored to almost all facilities and most homes. Crimea's energy company reported mass blackouts for consumers in all cities and districts of the annexed peninsula — besides Sevastopol, power outages were recorded in several districts. Monitoring channels reported that the port in Kerch was attacked and a fire was recorded at the Gvardeyskoye air base.
