In a concerning escalation of energy warfare, Russia has stepped up its campaign of targeting civilian petrol stations with drones and missiles, while Ukraine continues to strike Russian oil refineries. The attacks have resulted in fuel shortages across Russia, whereas in Ukraine, key roads have no functioning petrol stations due to the relentless strikes. The city of Kharkiv in northeastern Ukraine was hit by two drone attacks on Monday, wounding two people, and a similar attack outside Kryvyi Rih last week resulted in three fatalities. These attacks began in earnest in April and have become increasingly frequent. Notably, Russia has shifted from using smaller drones to more expensive and destructive Iranian-made Shahed drones, with one petrol station taking five hits. In response, Ukrainians are being advised to leave petrol stations when air raid alerts sound, and some key roads have no functioning stations left. The village of Opishnya in the Poltava region has had all its petrol stations destroyed. The Ukrainian authorities are stockpiling fuel in various locations as a countermeasure, while petrol stations in areas controlled by Ukraine are strictly adhering to working only during non-alert hours. So far, the drone strikes have not had a significant impact on fuel supplies in Ukraine, but the picture is vastly different in Russia where fuel shortages are prevalent almost everywhere due to the attacks on refineries and other infrastructure.
