Ukraine’s military has claimed to have sunk a submarine in Russian-controlled Sevastopol.
Kyiv also said they had attacked a southern Russian airfield and hit oil depots in Belgorod, Kursk and Rostov.
“A Russian submarine went to the bottom of the Black Sea,” the Ukrainian defence ministry said in a post on X on Saturday.
The submarine was purported to be the B-237 Rostov-on-Don, an improved Kilo-class attack submarine.
There was no immediate comment by Russia on the apparent Sevastopol attack.
Ukraine said that the submarine, which could launch Kalibr cruise missiles, had previously sustained significant damage in an earlier attack in September last year, but had since been repaired.
The estimated value of the submarine, which was hit on Friday, is €275 million.
Ukrainian forces also carried out strikes against an airfield in Russia’s Rostov Oblast, local media reported, supposedly hitting its ammunition depot storing glide bombs and other weapons.
Ukrainian President Volodymyr Zelenskyy praised the Ukrainian military after the claimed attacks.
“It is most effective when the consequences of the Russian war are brought back home to Russia,” he said in an evening address on Saturday.
