Authorities in western Afghanistan are investigating whether 100 schoolboys who were hospitalised on Saturday were poisoned, police said, according to Reuters. The boys, ages 10 to 14, fell sick after they ate beans from a vendor outside the school who told them the meal would help them pass their examinations in the western city of Herat, according to Abdul Jabar Rozi, Herat's police chief. The vendor was arrested later on Saturday and an investigation launched into whether the food was deliberately tainted, he said. "Enemies might be behind this," Rozi added.
