Hassan Noori, the Deputy for Technical and Operations of the National Emergency Organization, announced on Tuesday, August 14, that the number of people poisoned by chlorine gas in the city of Dezful has reached 509. According to the Mizan news agency, affiliated with the judiciary, he stated that 500 individuals were discharged after initial treatment, while 9 remain hospitalized in the Ganjouyan and Nabavi hospitals in Dezful. The Deputy of Emergency Operations mentioned that medical teams in Dezful are still on standby. Previously, officials in Dezful had reported that the pollution caused by the release of chlorine gas was contained by rescue and firefighting forces after four hours, and the chlorine gas cylinders were evacuated from the incident site on the morning of Sunday, August 22. According to the state news agency IRNA, the leak of chlorine gas from an abandoned warehouse belonging to the Dezful Raw Irrigation Company near the Rudband Square of the city caused respiratory issues for hundreds of people on Saturday night. The reports from this news agency and other Iranian media did not mention why the chlorine gas cylinders were left in this 'abandoned warehouse.' Meanwhile, the public and revolutionary prosecutor of Dezful announced that the chlorine gas leak incident is under investigation by the judiciary and a case has been opened in this regard. Ahmad Ghahramani told IRNA that based on initial evidence and hypotheses, and considering that the valve of the chlorine gas cylinder is missing, it is likely that 'an individual attempted to steal the valve, which led to the gas leak and created problems for citizens.' Habibollah Asafi, the governor of Dezful, also stated to IRNA: 'According to preliminary investigations, this incident occurred due to the tampering of an individual attempting to steal the valve from the chlorine gas cylinder in the warehouse of the old irrigation company in Dezful, and the thief fled due to the gas leak, which caused the gas to leak over a wide area of the region.'
