Officials and doctors say 89 Afghan school girls have been hospitalised in the third case of alleged gas poisoning in eastern Afghanistan in less than three weeks.
Dr Aziz Agha says scores of students have been admitted with symptoms such as headaches, vomiting and shivering. Afgha is treating the girls in Kapisa province.
Interior Ministry Spokesman Zemeri Bashary says the girls were sent to the hospital after they arrived at school on Tuesday to a strange smell in the yard. He says 89 schoolgirls were among the 94 patients. Three teachers and two guards are also sick.
The incident follows two cases of alleged gas poisoning - the most recent on Monday - at girls' schools in neighbouring Parwan province.
