Near Kursk airbase in southwestern Russia, an oil storage tank was set ablaze "due to a drone strike," the region's governor announced Tuesday through Telegram.
It comes one day after Moscow accused Ukraine of two drone strikes deep into its territory, suggesting that Kyiv is employing unexpectedly new methods by hitting military facilities deep within Russia, well beyond its borders.
"An oil storage tank caught fire near the airstrip in Kursk as a result of a drone strike," wrote the governor of the Kursk region, Roman Starovoit. "There were no victims. The blaze is being contained. All specialized services are operational on-site."
The airstrip is located around 100 kilometers from the Ukrainian border, on the outskirts of Kursk.
Monday, Russia's defense ministry accused Ukraine of being responsible for two drone attacks hundreds of kilometers inside Russian territory that resulted in the deaths of three individuals.
If accurate, these allegations could signal a significant change in the battle that escalated with Russia's full-scale invasion of Ukraine in February, as Ukrainian forces are now able and ready to strike targets within Russia.
Kyiv has not claimed responsibility for any of the three drone strikes; nevertheless, senior officials mocked the Kremlin following Monday's airfield explosions.
