Sources from Ukraine’s SBU security services told the Kyiv Post that it believed at least six planes had been destroyed and eight heavily damaged.
Russian sources did not acknowledge any damage at the military facility.
The Russian Ministry of Defence said on Friday its air defence downed 53 Ukrainian drones, including 44 in Rostov Oblast, six in Krasnodar Krai, one in Kursk, Saratov and Belgorod oblasts.
But the governor of Kursk, Roman Starovoyt, appeared to contradict that statement, saying four Ukrainian drones had been downed over the border region.
Roman Busargin, the governor of Russia’s Saratov region, reported a drone was downed in the city of Engels, home to another important air base, some 500 miles south-east of Moscow.
Kyiv’s forces have attempted to launch regular raids on Russian air bases used in long-range attacks against Ukrainian territory. Morozovsk was last hit in December.
