Russian drones struck gas stations in Kyiv for the second consecutive day, marking an escalation in Moscow's air campaign. Ukrainian officials said the attacks aimed to disrupt daily life and undermine civilian morale. In recent months, Russian forces have increasingly targeted urban gas stations, particularly in eastern and southern Ukraine, near the front lines. This strategy has also included strikes on food distribution centers, leading to empty supermarket shelves in Kyiv and other cities. As Russia's invasion enters its fifth year, Ukraine is working to strengthen its air defenses and has received additional support from Canada. In response to Russia's attacks, Ukraine has expanded its own military operations, launching long-range drones deep into Russian territory. On Thursday, Ukrainian forces reported hitting an oil refinery more than 3,000 kilometers (1,800 miles) away in Siberia, aiming to damage Russia's oil sector. These strikes have caused fuel shortages in Russia, one of the world's largest energy producers. According to the Center for Research on Energy and Clean Air, Russia's oil exports reached record lows in August, and the country has started importing fuel from South Korea and India. The nonprofit noted that Russia's fuel imports surged to a record 172,000 metric tons in August—more than seven times the previous monthly high. Ukrainian officials have warned citizens to avoid lingering near gas stations and other exposed infrastructure during air raid alerts. On Friday, drones hit two gas stations in Kyiv's Dniprovskyi and Obolonskyi districts within 10 minutes, injuring five people, including a rescuer. Analysts had long predicted that Russia would extend its attacks on gas stations to the capital as part of a broader campaign to intimidate civilians. Meanwhile, in central Ukraine, Russian drones killed five people and wounded 67 in Pavlohrad, where an official day of mourning was held on Friday. In Zaporizhzhia, a 32-year-old woman and her 10-year-old son were wounded in an overnight attack on a residential building and a shopping mall. Ukraine launched a major drone barrage overnight, with Russian air defenses intercepting 777 drones across 16 Russian regions, as well as occupied Crimea and the Azov and Caspian seas. Two people were killed and three wounded in a drone attack on the Tula region south of Moscow. A Ukrainian drone strike also caused a fire at the Saratov oil refinery in southwestern Russia, a facility that has been repeatedly targeted. The attacks continue to strain both sides, with Ukraine seeking to disrupt Russia's energy infrastructure while Russia aims to weaken Ukraine's civilian and military capabilities.
