London - International rights group Amnesty International condemned Iranian authorities on Friday for what it said was the "unspeakably cruel" blinding of a man on the grounds of retribution.
The man was forcibly blinded in his left eye on Tuesday under the principle of "qisas" - an eye for an eye - at a prison in Karaj, west of Tehran, Amnesty said.
The man had been convicted of throwing acid in another man's face in 2009, leading to a 10-year prison sentence, an order to pay blood money to the victim and the act of retribution.
