An investigation into the causes of the fire at an oil depot belonging to BRSM-Nafta is almost over, the cost of damages is being defined, Ukrainian Interior Minister Arsen Avakov has said.

"The investigation is virtually over… One remaining issue is the cost of damages," he said at a press conference in Kyiv on Tuesday.

Six people died because of the incident, 15 were injured. Containers with fuel had been burning for almost three days.
