Dozens of workers at a petrochemical center in southwest Iran were taken to the hospital on Saturday following a chlorine gas leak, according to state media.
The chlorine gas leak occurred at the Karun petrochemical center in the city of Mahshahr in the oil-rich province of Khuzestan, the official IRNA news agency reported.
The chlorine leak sickened 70 workers, according to IRNA.
A video received by Al Arabiya showed workers receiving treatment at a hospital. The workers are heard and seen coughing in the video. Coughing and shortness of breath are some of the symptoms of exposure to chlorine.
Another video received by Al Arabiya captured the chlorine gas leak. The video showed a yellow gas in the air at the petrochemical center. Chlorine gas appears to be yellow-green in color.
Earlier on Saturday, a power plant in the city of Ahwaz, the capital of Khuzestan, caught fire when a transformer exploded, IRNA said.
Iran has had dozens of mysterious fires and explosions across the country in recent weeks.

On June 25, another explosion took place close to a sensitive military site near Tehran which a defense ministry spokesman told state TV was caused by a tank leak at a gas storage facility.
