Iranian security forces fire teargas as girls clash with staff at Tehran school

Unverified footage shows armed police firing at least one canister after staff attempted to inspect students' phones

Iranian security forces fired teargas outside a girls' school in Tehran when clashes broke out after staff attempted to inspect students' mobile phones amid ongoing anti-government protests.

Iran's Ministry of Education said several students were treated by emergency services for a drop in blood pressure, but denied that security forces had entered the school.
