Ukrainian officials said a Russian strike killed one person in the Rivne region on Friday, with three more injured in overnight attacks on Kyiv Oblast. Hours later, a fire was reported at Russia's Afipsky oil refinery in Krasnodar Krai, extending a months-long campaign of cross-border strikes on energy infrastructure. Neither government has confirmed the cause of the refinery fire. Ukrainian officials reported Friday that a Russian strike killed one person in the Rivne region, marking the latest deadly attack in an active conflict now well into its fourth year.

Local authorities said three additional people were injured overnight in separate strikes on the Kyiv Oblast, though the full extent of damage to infrastructure in the area was still being assessed by emergency crews. Hours after the strikes on Ukrainian territory, a fire was reported at Russia's Afipsky oil refinery in the Krasnodar Krai region, according to local reports relayed by Euronews. The facility has reportedly been targeted in previous incidents during the war, as both sides have increasingly struck energy infrastructure far from the front line.

Neither Kyiv nor Moscow has formally confirmed responsibility or the precise cause of the blaze. The parallel incidents underline how the war has evolved into a broader contest over energy capacity, with refineries, power stations and fuel depots on both sides of the border now regularly drawn into the fighting. Diplomatic efforts to negotiate an end to the conflict, including talks reportedly planned in Abu Dhabi, continue alongside the ongoing strikes, with no ceasefire currently in effect.
