Iranian security forces have clashed with students at a university in the capital of Tehran in the latest protests in Iran linked to the death in custody of a young woman.
The woman, Mahsa Amini, died on September 16 after she was detained by the morality police for allegedly wearing her head scarf too loosely.
Since her death, Iran has seen a rare outburst of sustained public anger, driven in large part by Iranian women.

One of the videos showed security forces firing teargas to drive the students off the campus and the sound of what appeared to be shooting in the distance could be heard.
Another video showed security forces chasing dozens of students trapped in the university's underground parking. The account said dozens of students had been arrested.
Iranian state media described "reports of clashes" at the university and said the country's science minister visited the campus to check on the situation.
Students were protesting at numerous universities on October 2 and demonstrations were held in several cities, such as Tehran, Yazd, Kermanshah, Sanandaj, Shiraz, and Mashhad, with participants chanting "independence, freedom, death to [Supreme Leader Ayatollah Ali] Khamenei," earlier social media posts showed.
Iran Human Rights, a Norway-based group, in a statement said that "so far 133 people have been killed across Iran," including more than 40 people it said died in clashes last week in Zahedan, capital of the southeastern Sistan-Baluchistan Province.
