Iran has arrested 110 suspects in mass schoolgirl poisonings, police say

Iranian police said Wednesday that 110 suspects have been arrested in connection with the mysterious poisonings of thousands of girls in schools across the country.

Students say they have been sickened by noxious fumes in incidents dating back to November that have mainly occurred in girls' schools. Authorities say they are investigating, but there has been no word on who might be behind the incidents or what — if any — chemicals have been used.

Unlike neighboring Afghanistan, Iran has no history of religious extremists targeting women's education, even during the height of its 1979 Islamic Revolution. There have been no reported fatalities linked to the schoolgirl poisonings, and some officials have suggested that mass hysteria might have played a role.
