Tehran, Iran – Iran’s supreme leader, Ayatollah Ali Khamenei, has called for the perpetrators of schoolgirl poisonings to be punished as attacks spread across the country. Speaking on the sidelines of an annual tree-planting ceremony on Monday, Khamenei said the poisonings are a “major and unforgivable crime” and the perpetrators must face the “harshest punishment” for incidents that have spread fear among parents and throughout Iranian society. The supreme leader, however, did not discuss whether the poisonings originated from inside or outside the country – something senior officials have commented on
