At least four Iranian inmates died in a fire in Tehran’s notorious Evin prison overnight, the judiciary said Sunday, further stoking tensions one month into protests sparked by the death of Mahsa Amini.

The Iranian authorities blamed the fire on “riots and clashes” among
prisoners, but rights groups said they had little faith in the official version
of events.

“Four prisoners died due to smoke inhalation caused by the fire, and 61
were injured,” the judiciary authority’s website Mizan Online reported.
Four others were in “serious condition”, it said, adding that the fire had
been extinguished.

Prisoners’ relatives and rights groups voiced grave fears for the inmates,
and said authorities had used tear gas at the facility.

Gunshots and explosions were heard during the blaze from inside the
complex, illuminated by flames and smothered by smoke, in video footage posted
on social media channels.

The fire came after four weeks of protests over the death of 22-year-old
Amini, following her arrest for allegedly violating Iran’s strict dress code
for women.

The wave of demonstrations has turned into a major anti-government movement
in the Islamic republic, confronting its clerical leadership with one of its
biggest challenges since the ousting of the shah in 1979.

Evin, infamous for the ill-treatment of political prisoners, also holds
foreign detainees and thousands facing criminal charges.

Hundreds of those arrested during the recent demonstrations and in a
crackdown on civil society have been sent there.

“We do not accept official explanations,” the Norway-based non-government
group Iran Human Rights (IHR) said about Iran’s official comments, adding that
it had received reports that guards had sought to “incite” prisoners.

– ‘Arbitrarily detained’ –

There were also reports, backed by images, of explosions rocking the inside
of the prison complex, gunshots heard and even a projectile being fired from
outside into the jail.

“Prisoners, including political prisoners, are completely defenceless
inside that prison,” said Hadi Ghaemi of the New York-based Center for Human
Rights in Iran.

Iranian rights activist Atena Daemi, herself a long-time inmate of Evin,
wrote on Twitter that in the early hours of Sunday several buses and ambulances
were seen leaving the prison.

She said some prisoners in Ward 8, which houses political detainees, had
been transferred to another jail.

IHR reported that inmates’ relatives gathered outside Evin on Sunday,
seeking information about their loved ones.

Kazem Gharibabadi, deputy head of Iran’s judiciary, visited the facility
and blamed “those incarcerated in Ward No. 7” for the unrest. He said the fire
“did not spread to other wards”.

“The security and safety of prisoners is of paramount importance,” tweeted
Gharibabadi, who is also secretary-general of Iran’s High Council for Human
Rights.

Citing a Tehran prosecutor, the official IRNA news agency said the clashes
had “nothing to do with the recent unrest in the country”.

The four inmates who died had been convicted of robbery, Mizan said.

Evin prison holds French-Iranian academic Fariba Adelkhah and US citizen
Siamak Namazi, whose family said he was taken back into custody days ago after
a temporary release. Namazi’s US attorney Jared Genser said he had spoken to
his family, and that he was unharmed.

France said it was following “with the greatest attention” the situation of
French citizens “arbitrarily detained” in the facility.

– In ‘distress’ –

Australian academic Kylie Moore-Gilbert, who was held in Evin for most of
her 800-plus days behind bars in Iran, told AFP she had heard that all the
women political prisoners were safe.

But supporters of Austrian prisoner Massud Mossaheb said he was suffering
from the effects of smoke inhalation and tear gas.

“He can barely speak… He is in big distress,” their Twitter account said.

Hossein Sadeghi, the father of rights activist Arash Sadeghi who was
arrested days ago, said he had spoken with his son and confirmed he was alive.
Amnesty International’s secretary general Agnes Callamard stressed that
Iranian authorities “have the legal obligation to respect and protect the lives
and wellbeing of all the prisoners”.

Rights groups reported night-time protests in Tehran in solidarity with
Evin detainees and more demonstrations were held Sunday, including at Tehran
University.

At least 108 people have been killed in the Amini protests, and at least 93
more died in separate clashes in Zahedan, Sistan-Baluchestan province,
according to IHR.

The European Union has agreed to level new sanctions, a move expected to be
endorsed by its foreign ministers Monday.

“We expect maximum transparency on the situation” at Evin prison, EU
foreign policy chief Josep Borrell said Sunday on Twitter.
