Ukraine said it launched overnight attacks far inside Russian territory, targeting a major oil refinery and the Engels airfield in the Saratov region. The claim was presented by President Volodymyr Zelensky, who identified the air base and the refinery as key targets in the operation.

Engels airfield is notable because it hosts Russian strategic aviation, making it one of the more sensitive military sites mentioned in the report. The refinery strike also points to Ukraine's continued focus on energy infrastructure that can have military and economic importance.

On the Russian side, Moscow reported eight deaths linked to the attacks. The trimmed report did not include full details on where those deaths occurred or the extent of damage at the sites named by Ukraine.

The exchange highlights how the war is continuing to reach beyond front-line areas, with Ukraine emphasizing its ability to hit targets deep inside Russia. It also underscores the growing importance of air bases and fuel facilities in the broader conflict.
