Iran is experiencing another wave of suspected poison gas attacks targeting female students in several cities.
Over the weekend a security official said that students “smelled an unpleasant odor, had a burning sensation in the throat and felt weak” they were sent to the hospital.
The previous wave of gas attacks began in November of last year and affected hundreds of schoolgirls across Iran. A fact-finding committee is expected to report to parliament in about two weeks.
Iranian authorities have already arrested 110 people accused of being linked to these attacks.
Authorities have accused the Islamic Republic’s “enemies” of using the attacks to undermine the clerical establishment. But suspicions have fallen on hardline islamist groups within the country.
