These riots in an Iranian prison are the latest since protests erupted three months ago in following the death of Mahsa Amini after she was arrested by the morality police for not adhering to the Islamic dress code for women.
The Oslo-based Organization of Iran for Human Rights (IHR) said in a statement that rioting erupted when prisoners protested the transfer of a prisoner in isolation before his imminent execution.
However, Iranian authorities said one of the detainees was killed by stone-throwing after clashes between prisoners.
The chief judge of Alborz province, where Karaj is located, said the riots had started in the drug department and prisoners set fire to blankets, causing a fire. He added that calm has returned to the prison.
In October, at least 8 prisoners died in a fire in Evin prison in Tehran, which according to the authorities was started by “thugs”.
Non-governmental organizations have put in doubt the official version of events in Ewen, where foreigners are imprisoned and known to mistreat political prisoners.
In the same month, other incidents broke out in the prison of Rasht, capital of the province of Gilan, in the north-west of the country.
The Human Rights Organization in Iran said prisoners in Karaj chanted anti-regime slogans, including “Death to the dictator”, and blocked doors and smashed surveillance cameras.
He added that the deceased prisoner’s name was Mohsen Al-Mansouri, who died of a gunshot wound to the head, while 17 wounded prisoners were transferred in hospital. Authorities said the wounded had minor injuries and the identity of the prisoner facing execution has not been determined.
According to the United Nations, in At least 14,000 people were arrested in Iran as part of the crackdown on protests that erupted on September 16, which, according to activists, has led to overcrowding in prisons.
On Friday, Amnesty International said at least 26 people were at risk of execution in relation to the protests. Western countries have condemned the execution of two protesters in Iran this month.
