Ukraine struck an oil terminal in Russia's southern Krasnodar region, Reuters and other outlets reported on the 15th local time.
The General Staff of the Armed Forces of Ukraine said the attack caused a fire in a village in the nearby Volna area.
According to the Ukrainian outlet Kyiv Independent, two people were injured and 126 residents evacuated because of the fire.
The area also came under Ukrainian attack on the 21st of last month, leaving three dead and eight injured, with damage continuing.
Ukraine is focusing strikes on energy infrastructure and the "shadow fleet" to cut off Russia's war financing. The shadow fleet refers to vessels that transport Russian oil by evading international sanctions, frequently changing their flag so that ownership information is often unclear.
Meanwhile, both sides carried out drone attacks the day before as well.
According to the State Emergency Service of Ukraine, the port city of Odesa region was hit by a Russian drone attack, and an elderly woman in an apartment was killed.
In Russia's border region of Bryansk, one civilian riding in a vehicle was killed in a Ukrainian drone attack.
