> Igor Volobuev, a former Gazprom and Gazprombank executive who now operates drones for Ukraine’s army, says the underground group Black Spark provides Ukrainian forces with intelligence on vulnerable refinery sites. He says the group has helped strike nine Russian refineries since September 2025, including Omsk, while operating independently of Ukraine’s military.
