Iran’s supreme leader Ayatollah Ali Khamenei called the poisoning of schoolgirls across the country an “unforgivable crime”. These are his first comments on the issue that fuelled anger against the government at home and abroad. Speaking at a tree-planting ceremony at his office, Mr Khamenei said authorities “should seriously pursue the issue of student poisoning”. “If it is proven that the students were poisoned, the perpetrators of this crime should be severely punished. There will be no amnesty for these people,” he added.
