Ukraine has carried out overnight strikes deep inside Russia, hitting a major oil refinery and an airfield housing Russian strategic aviation, according to Ukrainian President Volodymyr Zelensky. The Engels airfield and the refinery, both located in the Saratov region about 600 km (373 miles) from Ukraine's border, were targeted. Additional strikes hit an oil depot in the Kaluga region and a drone launch site in Bryansk.

The Ukrainian military stated that its attack caused a blaze at the Engels airfield, which is one of the main bases for Russia's strategic aviation. It noted that Tu-95MC and Tu-160 bombers regularly use Engels to launch missile strikes against Ukraine.

Russia reported that eight people were killed in the Ukrainian strikes and claimed to have shot down or intercepted 635 drones. Moscow also reported another strike on a warehouse belonging to Russia's largest online retailer, Wildberries.

Meanwhile, Moscow said its forces attacked two Ukrainian ports and two vessels in the Black Sea overnight. Later on Sunday, Ukraine reported that one person was killed in a Russian strike on a postal terminal near the northeastern city of Kharkiv.

President Zelensky described the Ukrainian strikes as "our long-range sanctions" against Russian facilities that he says finance Moscow's war effort. A drone attack also caused damage to civilian infrastructure in Saratov and Engels.
