A massive wave of 350 Ukrainian drones targeted Russian territory, coinciding with the opening of parliamentary and local elections that run through Sunday, according to regional officials and international news agencies.
Infrastructure Impact in Yaroslavl and Tula Oblasts
The heaviest economic impact struck Yaroslavl Oblast, where a Ukrainian drone strike ignited a fire at the Slavneft-Yaroslavnefteorgsintez oil refinery. According to Reuters sources, the blast damaged the primary refining unit AVT-3, which possesses a daily processing capacity of 17,140 metric tons, representing approximately 40% of the plant’s total refining output. Yaroslavl Oblast Governor Mikhail Yevrayev stated on Telegram that air defenses downed 65 drones across the region, adding that the refinery fire was extinguished with no reported injuries, though the highway from Yaroslavl toward Moscow faced a temporary closure. Ukrinform reported that the facility fully suspended crude processing following the attack. Meanwhile, Tula Oblast Governor Dmitry Milyaev reported that air defense units intercepted 40 drones south of Moscow.
Power Disruptions and Military Site Damage in Rostov
Ukrainian drone operations also targeted Rostov Oblast, following a strike on a military airfield that disabled two aircraft and three helicopters. According to regional reports, drone debris damaged a transformer station, triggering a power outage across four districts in Rostov-on-Don.
