Reyhaneh Jabbari, 26, has been hanged in a Tehran prison in Iran today after being found guilty of murdering an older man in what she says was self defense. The man is said to have been trying to sexually abuse her.

An international campaign urging a reprieve has brought a temporary stay in execution, which was due to be carried out on 30 September but was postponed for 10 days, but failed to prevent the implementation of the death sentence for the young woman who -Human rights group Amnesty International said- was convicted after a deeply flawed investigation.

Efforts for clemency had intensified in recent weeks. Jabbari's mother was allowed to visit her for one hour on Friday, Amnesty said, a custom that tends to precede executions in Iran.

Government news agency Tasnim said on Saturday that Jabbari had been executed after her relatives failed to gain consent from the victim's family for a reprieve. Jabbari's mother, Shole Pakravan, confirmed the execution in an interview with BBC Persian.

Jabbari was arrested in 2007 and sentenced to death in 2009 by a Tehran criminal court for the murder of Morteza Abdolali Sarbandi, a doctor and a former Intelligence Ministry employee. Later that year the Supreme Court affirmed the death sentence. Jabbari admitted stabbing Sarbandi in the neck, but says that he attempted to sexually assault her. She also said that a third person in the room may have caused Sarbandi’s death. Jabbari’s lawyers contend that the judiciary did not properly investigate the cause of death and deprived their client of a fair trial. Tehran’s prosecutor’s office had been reviewing the case.
