Rosneft has suspended crude intake at its 140,000-barrel-a-day Saratov refinery after a weekend wave of Ukrainian drones set parts of the Volga-region plant ablaze. Regional governor Roman Busargin said the attack killed one person and damaged an unnamed “industrial enterprise”; flight-tracking data showed temporary disruptions at the city’s airport. Videos posted overnight on 10 August and thermal imagery from NASA’s FIRMS system showed multiple impacts and towering columns of smoke across the refinery complex. The strike is the latest in a series of Ukrainian long-range drone operations that have reached targets roughly 700 kilometres from the front line. Russian officials also reported three deaths in separate drone incidents in the Tula and Nizhny Novgorod regions on 11 August. One of the devices hit the Arzamas Instrument-Building Plant, a sanctioned manufacturer of electronics used in cruise missiles and fighter aircraft, triggering secondary explosions. Kyiv expanded the campaign on 13 August, saying it struck the Unecha oil-pumping station in Bryansk, a critical hub feeding the Druzhba pipeline to Europe. Bryansk authorities confirmed a fire at the site but said transit volumes were unaffected. The same night, debris from intercepted drones ignited a small blaze at the privately owned 100,000-barrel-a-day Slavyansk refinery in Krasnodar. The attacks have disabled three Russian refineries since the start of the month, adding to domestic maintenance outages that helped push the country’s seaborne fuel exports 6.6% lower in July, according to industry data compiled by Reuters. Analysts say further hits on refining capacity could prompt Moscow to divert more crude to export markets while tightening supplies of gasoline and diesel at home.
