Around 200 students and at least one teacher in 12 different girls’ schools have reported symptoms such as nausea, headaches, coughing, difficulty breathing, heart palpitations, and lethargy since November 30 when 18 students of a secondary school fell ill with similar symptoms. Majid Mohebbi, told the Revolutionary Guards linked Tasnim news agency Monday that MRI and other tests carried out on the affected students all came out normal, and nothing was detected in samples taken from the students and the classrooms. Tasnim and other state media refrain from mentioning that the mysterious poisonings happen only in girls’ schools, but many believe it may be intentional targeting of female students
