MOSCOW (Sputnik) — Bou Ali Sina petrochemical complex is located in Petrochemical Special Economic Zone in Mahshahr county.
"If this fire is not extinguished, it might also be spread to other areas," Mahshahr County governor Mansour Qamar said as quoted by IRNA News Agency.
The fire has been most likely caused by the paraxylene, a highly flammable hydrocarbon, leakage. No casualties has been reported so far.
