More than 60 schoolgirls were poisoned in Iran on Saturday, according to local media. The suspected poison attacks against schoolgirls in particular have shaken Iran since November last year.
Since then, more than 5,000 students have suffered symptoms such as dizziness, nausea, headaches and difficulty breathing. Iran's supreme leader, Ayatollah Ali Khamenei, called early last month for "severe penalties" up to the death penalty against those found to be responsible for the poisonings, which he described as "unforgivable crimes"
