Ukraine's Security Service says drones from its Special Operations Centre Alpha struck the Samara oil pipeline hub near Provet in Samara Oblast on 13 November, hitting oil storage tanks. The station blends crudes of different sulphur levels into Urals — up to half of Russia's oil exports — and, per the report, strikes begun in late October threaten a fuel crisis and may have paralysed facilities producing about 55% of Russia's petrol.
