Ukrainian forces reportedly conducted overnight strikes on September 25, 2026, targeting an oil refinery in Perm and an electronics components factory in Ulyanovsk, both located deep within Russia. Eyewitnesses reported a fire at the Perm refinery, situated approximately 1,500 kilometers (900 miles) from Ukraine's border, according to the Telegram channel Exilenova Plus. The Iskra electronics plant in Ulyanovsk, which manufactures components for communications and radio technology, was also reportedly hit. Explosions were heard in Voronezh as air defenses were engaged, though it is unclear if any targets were damaged there. Authorities have not yet commented on the reported strikes, and the Kyiv Independent could not immediately verify the details. Ukraine has been conducting regular strikes on military infrastructure within Russia and occupied territories to degrade Moscow's war-fighting capabilities. This follows alleged drone attacks on oil depots in Russia's Rostov Oblast and Krasnodar Krai on September 24, and a strike near an oil refinery in Ufa on September 23, which is located about 1,200 kilometers (750 miles) from the border. Meanwhile, Russia has continued its attacks on Ukrainian cities, with two people killed and eight injured in missile strikes on Kyiv on September 24 that damaged residential buildings and a maternity hospital.
