A teenage Iranian girl who fell into a coma after an alleged altercation with morality police earlier this month has died, state media and activists say.

Armita Geravand, 16, collapsed after boarding a Tehran metro train on 1 October.
Activists accused morality police of assaulting her for not wearing a hijab. She died on Saturday morning after "suffering from brain damage", according to state news agency.
 
 Norway-based human rights group Hengaw, which focuses on Iran's Kurdish ethnic minority, said it had received a report that Armita had "become the latest victim of forced hijab and has died after 28 days of hospitalisation".
It called for an independent medical team from Médecins Sans Frontières and the International Committee of the Red Cross to investigate her death.
"The regime Iran has attempted to distort the narrative surrounding the government's involvement in her death," the group said.
Many Iranians have drawn parallels with the case of Mahsa Amini, a young woman who died in custody in September 2022 after being detained by morality police in Tehran for allegedly wearing her hijab "improperly".
Anti-government protests, which are still taking place, erupted across the country when Amini died after three days in a coma. Hundreds of people have been killed and thousands detained in a violent crackdown by security forces.
