Ukrainian drone strike hits Yaroslavl refinery and Vologda acid pipeline

Ukrainian‑launched UAVs attacked an oil refinery in Yaroslavl, igniting a large fire that prompted an emergency response. In the Vologda region, a separate drone strike ruptured a pipeline carrying sulfuric acid, causing a leak that was later contained. Five people were hospitalized with burns, according to the regional governor. Russia’s defence ministry reported that air defence forces shot down 203 Ukrainian drones over Russian territory that night. The incidents underscore the escalating cross‑border drone warfare between Russia and Ukraine.
