A massive Ukrainian drone strike has hit deep inside Russia’s Bashkortostan region, targeting the Sterlitamak petrochemical plant, nearly 1,500 km from the frontlines. Explosions rocked the Urals overnight as Kyiv’s drones penetrated Russian airspace, exposing the vulnerability of Putin’s industrial core. Officials confirmed no injuries, but structural damage was extensive. This marks Ukraine’s deepest strike yet — a bold escalation in the drone war that is reshaping modern conflict.
