MOSCOW, June 25, 2026 (BSS/AFP) - Debris from a drone strike triggered a fire at an oil depot in Russia's southern Krasnodar Krai region, authorities said Thursday.

Ukraine has stepped up attacks on Russia in recent months in retaliation for Moscow's near-daily air barrages of drones and missiles throughout its invasion, now in its fifth year.

Kyiv insists that the Ukrainian army first and foremost targets military installations and energy infrastructure, in a bid to deprive the Kremlin's war chest of vital fossil fuel revenues.

"Following the fall of UAV debris, a fire broke out at the Poltavskaya oil depot," Aleksandr Kharitonov, head of Krasnoarmeysk district in Krasnodar Krai, wrote on Russia's state-run Max platform, without specifying the origin of the drone.

Minutes later, Ukraine's emergency services said that a Russian attack caused a fire at an industrial facility, where firefighters extinguished the blaze with no casualties reported.
