From the beginning, I stick to the version that it was an accident , caused by static electricity.
This is what the ammunition expert Nayden Iliev said on the air of BNT regarding the explosions in the warehouses with pyrotechnics near Elin Pelin Station.
"Fireworks are ignited by a spark, by fire. Obviously, the professionals who worked there would neither smoke nor light a fire in the warehouse. So static electricity is the only credible version of what happened," he was emphatic.
