The suspicious intoxication of schoolchildren resumed on Monday at the first day of school opening after two weeks of Newroz break in Iran.
The Hengaw Human Rights Organization reported that dozens of schoolgirls were hospitalized in Naqada city after a poison attack on their school on Monday.
Thousands of Iranian students, mostly schoolgirls, were affected in the past months by a wave of poison attacks, with symptoms including nausea, headaches, coughing, breathing difficulties, and heart palpitations.
Schoolgirls have been on the forefront of protests that have rocked the country following the death of 22-year-old Jina Mahsa Amini in morality police custody in September after the young Kurdish-Iranian woman was arrested for allegedly not wearing her hijab properly.
