A huge fire has broken out at Iran’s notorious Evin prison – where political prisoners and anti-government activists are held.
Gunshots are reported to have been fired as the blaze took hold at the jail in the capital Tehran on Saturday.
An alarm was heard as the US-based Centre for Human Rights in Iran claimed an “armed conflict” was taking place behind the prison walls.
Shots are said to have first been heard in Ward 7 of the jail, according to unverified reports.
Thick plumes of smoke billowed from the prison, where now freed Nazanin Zaghari-Ratcliffe was detained.
At least eight people are said to have been injured in the blaze, but no fatalities have yet been reported, according to state-run IRNA agency.
IRNA reported there were clashes between prisoners and personnel in one ward.

Eyewitnesses said roads to the prison were blocked with at least three explosions heard in the area.
Heavy traffic built up near the prison with motorists honking their horns in solidarity.
The internet is also said to have been blocked after the fire started.
The blaze happened as violent anti-government demonstrations intensified across the country for a fifth week, sparked by the death of Mahsa Amini, with children among the dozens dead.
