Ukrainian drones attacked a gas plant in Russia’s Orenburg region, the local governor said on Sunday, causing a fire in a workshop that emergency services were working to put out.
The governor, Yevgeny Solntsev, said on his official Telegram channel that none of the plant’s employees were injured in the attack, which left the plant partially damaged.
Solntsev said earlier this month that Ukrainian drones had attempted to attack an unnamed industrial facility in the Russian city of Orsk, near the border with Kazakhstan.
An unverified video posted on Telegram at the time showed an object crashing into a facility identified as the Orsknefteorgsintez oil refinery in Orsk.
Ukraine has stepped up attacks on Russian refineries and other energy facilities since August to try to disrupt oil supplies and deprive Moscow of funding.
