"Girls fell to the ground", this is how a witness describes the poisoning of young people in Iran

"It was a terrible situation. Girls fell to the ground and cried, some couldn't walk, they really didn't want to be separated," says a witness who saw poisoned students at a school in Qom, Iran.

This has not been an isolated case and, according to sources from the semi-official Mehr News, there would be almost 900 students affected throughout the country.
