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.
Women have played a prominent part in the protests, removing and burning veils. The deaths of several teenaged girls reportedly killed during protests have fuelled more anger.
Demonstrations continued on Monday, with a rally at a university in the western city of Hamedan, and students shouting down a government spokesman who visited a Tehran university, according to students and rights groups.
The education ministry said there was a clash at the Tehran high school between staff, students and parents after the school principal insisted on checking the girls' phones.
The widely followed activist Twitter account Tasvir1500 said uniformed forces attacked the school and at least one girl was wounded, but the city police denied their account.
"After news of a conflict near a high school ... police were dispatched to the area and investigated the issue which turned out to be a fight between a number of thugs," Tehran police said, adding that agitators were identified and arrested.
