Dozens more schoolgirls in Iran have been taken to hospital after suspected poison gas attacks.

Hundreds have been affected since the end of November – suffering from symptoms like nausea, dizziness and trouble breathing.

The Iranian health minister has announced an official investigation, amid speculation that deliberate poisonings are being carried out to close schools down and parents are getting increasingly concerned.
