In recent months, drone attacks targeting energy facilities within Russia's borders have increased in frequency.
Ukraine's military intelligence agency (HUR) claimed on May 13 it was behind the attack on the oil refinery in Volgograd. The Kaluganefteprodukt oil depot and the Novolipetsk metallurgical plant were also reportedly struck by drones.
Two days before, the Security Service of Ukraine (SBU) attacked an oil refinery, GazpromNeftekhim Salavat, in the Republic of Bashkortostan, and two oil depots in Krasnodar Krai, according to the Kyiv Independent's source.
Strikes against Russian energy targets have prompted criticism from U.S. officials, who have made it clear that Washington does not support Ukraine's attacks on oil refineries, citing fears that it could threaten the global energy market.
In response, President Volodymyr Zelensky said that Kyiv has the right to use its ownweapons to strike deep inside Russia.
