A long-range drone attack battered one of Russia’s crucial oil‐processing sites late Monday, sparking a large fire that sent black smoke over the adjoining industrial zone. The facility, operated by a major Russian oil producer, sustains output of gasoline, diesel and other refined fuels and sits deep within Russia’s internal supply chain. Local residents heard several explosions before emergency services scrambled to douse the blaze. The regional governor confirmed damage to infrastructure but said no fatalities were reported. Ukraine’s military previously said its drones were targeting Russian fuel sites to disrupt their war-linked economy.
