Four prisoners have died and 61 have been injured following a major fire at Iran’s notorious Evin prison, according to an Iranian state news agency.
Sources inside the prison – which is known for housing political prisoners – have told BBC Persian the number of casualties is higher.
Videos shared online showed flames and smoke at the site in Tehran, and gunshots and explosions could be heard.
The fire followed weeks of anti-government protests across Iran.
Hundreds of those taking part in protests have been sent to Evin prison. It is not known whether the situation at the jail is linked to the demonstrations.
