A drone attack in Taganrog, in Russia's Rostov Oblast, killed the chief engineer of an electrical substation and injured four other people, the regional governor said. The overnight strikes on Nov. 15 damaged two electrical substations, including one supplying power to railway infrastructure. A fire broke out at a substation in the city's Shubin district, while power lines between the Taganrog-Passenger and Mikhailovka railway stations were left without electricity. The attack also hit a section of the R-280 highway when a bridge over railway tracks in the Neklinovsky district was struck. Traffic across the bridge was closed, and vehicles were diverted through Taganrog and the village of Pokrovskoye. In total, five vehicles were damaged, including four near the bridge and one at a gas station, after drone debris fell on a vehicle on a highway and at a gas station. Three men and one woman were hospitalized. The governor said Russian air defenses destroyed about 50 drones overnight across Taganrog, Rostov-on-Don and seven districts of Rostov Oblast. He warned that the threat of further drone attacks remained. Independent outlet ASTRA, using its own open-source analysis, identified the 220-kilovolt Taganrog-10 substation as a likely target, saying it supplies electricity to Taganrog's industrial zone, including the TAGMET plant. Ukrainian forces have targeted infrastructure in the region in the past, and an earlier Nov. 8 attack damaged a bridge and power stations, according to Russian authorities. Ukraine’s military had not publicly claimed responsibility for the latest attack at the time of reporting.
