Iranian security forces have opened fire on people at a metro station in Tehran and beaten women who were not wearing mandatory hair coverings as protests over the death of Mahsa Amini entered a third month.

Footage shared on social media showed passengers running towards exits, with many falling and being trampled, after police opened fire on a crowded platform. Police were also filmed through train windows marching through carriages and beating women with batons.

Amini, a 22-year-old Iranian woman of Kurdish origin, died in the custody of the morality police on 16 September after her arrest for an alleged breach of Iran’s strict dress code for women.

More than 300 people have been killed by security forces over two months of protests, according to the Oslo-based group Iran Human Rights (IHR). The group says 15,000 people have been arrested, a figure the Iranian authorities deny.

Five protesters have so far been sentenced to death.
