Watch the moment a strike hits the Russian oil depot. THIS is the moment a Russian oil depot exploded in a huge fireball in yet another humiliating blow to Putin. Plumes of black smoke could be seen rising into the sky in Vyborg after the explosion at the oil refinery near the Nato border with Finland. Dramatic footage showed the oil depot engulfed in a raging inferno. Leningrad regional governor Alexander Drozdenko denied a Ukrainian kamikaze drone had hit the facility. He also denied there was a fire and claimed "there was a bang due to the use of pyrotechnics"....
