Ukraine's General Staff confirmed military and security services conducted an overnight strike on Russia's only operating oil refinery in Rostov Oblast.
Russian authorities confirmed a massive drone attack on Rostov Oblast facilities last night, with strikes hitting Novoshakhtinsk oil refinery and reportedly targeting military airfields.
Ukraine allegedly struck three fuel facilities in Russia with drones overnight on 6 June - refineries in Novoshakhtinsk and Slavyansk-na-Kubani, and a depot near Stary Oskol.
