Ukraine says it has carried out another long-range drone strike targeting Russian energy infrastructure, reporting damage to a refinery inside Russia. Multiple outlets cite Kyiv’s position that the attack triggers a fire at the site, producing heavy black smoke. The reports describe the strike as part of a broader escalation in Ukraine’s retaliatory long-range campaign in recent weeks, with a particular focus on oil and refinery sites. One outlet specifies the refinery is located about 800 km inside Russian territory. The articles do not provide independent confirmation of the extent of the damage or details about casualties. Russian officials and counterclaims, if any, are not included in the excerpts provided. Overall, the coverage presents the incident as the latest in a series of attacks attributed to Ukraine that aim to disrupt Russia’s oil infrastructure, while emphasizing that Ukraine characterizes the strike as part of a sustained pattern rather than an isolated event.
