Ukraine's Military said Saturday that it sunk an underwater submarine near Sevastopol in the Russian controlled region, destroyed a Russian airfield in southern Russia, and attacked oil depots, fuel storage and lubricant facilities located in Belgorod and Kursk regions.

The defence ministry announced in a posting on X that a Russian attack submarine, the B-237 Rostov on Don, had reached the Black Sea's bottom.

According to the military general staff, the attack at Sevastopol's port caused significant damage to four S-400 "Triumf", anti-aircraft launchers.

Russia has not yet commented on the Sevastopol incident.

The military also said that it had attacked a Morozovsk airport ammunition depot, where Russian troops stored guided aerial weapons, amongst other items, and several oil storage and depots.

The Russian combat aircraft must be eliminated wherever they are, using all means possible. Also, it is fair to attack Russian airfields. We need a joint security solution, and we must work with our partners to find it," Ukrainian president Volodymyr Zelenskiy said on Telegram.

Ukrainian President has asked his Western allies repeatedly for permission to strike military targets near the border, as well as long-range against Russia.

On Saturday, he said that Russian forces used more than 600 guided aerial weapons to attack Ukraine during the last week.

According to a Ukrainian military report, the attack on oil depots, fuel storage and lubricant facilities in Belgorod and Rostov region set at least two tanks ablaze.

Local officials in Russia reported that a drone strike caused tanks to catch fire at a fuel depot located in Kamensky District of Rostov Region.

A drone launched from Ukraine caused an explosion at a depot for oil in Belgorod, according to the regional governor. The fire has been extinguished. No one was hurt.

Ukraine's use of drones has increased dramatically this year in order to target Russian oil installations. The aim is to destroy sites that fuel Russian forces as well as the economy, during Moscow's 30-month long invasion. Reporting and editing by Gareth Jones, Frances Kerry and Elaine Monaghan.
