A crisis over suspected poisonings targeting Iranian schoolgirls escalated Sunday as authorities acknowledged over 50 schools were struck in a wave of possible cases. The poisonings have spread further fear among parents as Iran has faced months of unrest.
It remains unclear who or what is responsible since the alleged poisonings began in November in the city of Qom. Reports now suggest schools across 21 of Iran's 30 provinces have seen suspected cases, with girls' schools the site of nearly all the incidents.
