Chlorine blast poisons 200+ Iraqis
Baghdad - Officials say more than 200 people were poisoned by a chlorine gas explosion at a water purification plant in southern Iraq.
Dr Saadoun al-Aalak, deputy director of Al-Sadr hospital in Amarah, said no one died in the Thursday evening blast at the plant.
He said four people who were hospitalised overnight in critical condition from breathing the poisonous gas were released on Friday morning.
The provincial governor, Sheyaa al-Sudani, says 200 poisoned Iraqis initially sought medical treatment but most recovered quickly.
The cause of the blast in Amarah, about 320 kilometres southeast of Baghdad, was not immediately known, but there was no immediate indication of an attack.
