Since late November many schools, mostly for girls, have been affected by sudden poisoning incidents from gases or toxic substances, in some cases causing fainting and hospitalisation among the students.

At least “60 students were poisoned in a girls’ school in the town of Haftkel” in the oil-rich southwestern province of Khuzestan, state television’s Irib news agency cited a local official as saying.

A number of schoolgirls were poisoned in “five schools in Ardabil in the northwest”, where the victims showed symptoms of “anxiety, shortness of breath and headaches”, a provincial medical official told the news agency.

In the northwestern town of Urmia, capital of West Azerbaijan province, “a number of schoolgirls were taken to hospital today after feeling sick”, Ilna news agency reported without further elaboration.

According to an official count provided on March 7, “more than 5,000 students” have been affected by similar poisonings in more than 230 establishments, located in 25 of the country’s 31 provinces.

Yesterday MP Hamidreza Kazemi, the head of the national fact-finding committee formed to investigate these cases, specified that “the final report” would be published “in two weeks”.
