Ukrainian drones conducted a second day of heavy attacks on Russian oil refineries, causing damage to Rosneft's largest refinery in Ryazan. The drone strikes also halted operations at the Novoshakhtinsk refinery in the Rostov region. Following the previous day's attack on Lukoil's NORSI refinery, these incidents mark a serious uptake in attacks on Russia's energy sector. Oil prices rose by 2%, reflecting concerns about potential supply disruptions.
