A car explosion near the Russian city of Yekaterinburg killed a driver and critically injured Vladimir Tkachuk, head of a defense firm producing "Ghoul" attack drones for the Russian military, Russian media reported on Aug. 5. "The general director of Uraldronzavod, which produces Ghoul drones, Vladimir Tkachuk, was injured in a car explosion," Russian state news agency TASS reported, citing emergency services. Russian officials have not publicly identified a suspect or motive. Uraldronzavod manufactures the low-cost Ghoul family of FPV (first-person-view) attack drones, which Russian forces use against Ukrainian troops and equipment across the front line. Russian military officials and other figures involved in Moscow's full-scale invasion have previously been targeted in car bombings and other attacks, sometimes in Ukrainian-led operations.
