Iranian security forces fired tear gas near a girls' school in Tehran on Monday, according to videos posted on social media, after a dispute between authorities and students over their mobile phones amid ongoing anti-government protests in Iran.
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.
Videos circulating on social media showed heavily armed security forces outside the school. One clip showed them on motorbikes and firing at least one teargas canister. Reuters could not independently verify the authenticity of the footage.
Unrest ignited by the death of Mahsa Amini, a 22-year-old Kurdish Iranian woman who was detained by the Islamic Republic's morality police for "improper attire" and died in police custody, has swept Iran for five weeks. Rights groups say more than 200 people have been killed in the crackdown.
