Invading Russian forces hit an oil depot and a factory in Dnipropetrovsk Oblast during a late-night airstrike, Dnipropetrovsk Governor Valentyn Reznichenko wrote on Facebook on April 6.
“A fueled oil depot has been destroyed," he said.
"Rescue teams are still dousing the flame at the factory. There is a big fire there. The fuel is on fire."
Reznichenko added that the number of victims was being specified.
The Russian air force has a significant advantage over Ukrainian air assets. Ukraine has been asking for increased anti-air defense systems, and fighter jets, from the West, to counter this advantage.
Partner nations have yet to provide Ukraine with these capabilities.
