The Ukrainian military has carried out attacks in the Caspian Sea damaging three Russian oil platforms, the General Staff in Kyiv says on Telegram.
The platforms, belonging to Russian oil company Lukoil, are used to supply Russia's forces in Ukraine, the General Staff said.
The military said it hit V Filanovsky, Yuri Korchagin and Valery Grayfer platforms.
Ukraine gave no details of the type of attack but claimed "direct hits," which makes the use of long-range drones plausible.
"The extent of the damage is being assessed," it said.
The military's information could not be independently verified.
The Russian military generally does not provide information on damage from Ukrainian attacks.
Ukraine has repeatedly targeted oil and gas industry facilities in Russia to complicate supplies for occupying troops.
