The BBC is reporting that more than 100 schoolgirls in northeastern Afghanistan have been hospitalised in what has been theorised as a poison attack.
The health director of Takhar province said the girls fell ill shortly after drinking water at their school.
An education official in Kabul said preliminary investigations suggested the water had been poisoned.
A local official in Takhar suggested that people opposed to education for girls were responsible.
Similar events have been reported before, but no conclusive evidence of poisoning has been found.
The official said 40 girls were treated and then discharged but 100 other females including teachers have been kept in hospital, after complaining of severe nausea, headaches and dizziness.
