The execution of Reyhaneh Jabbari, the Iranian woman who was sentenced to death for killing her alleged attempted rapist, has drawn worldwide condemnation.
Jabbari was hanged in a Tehran prison on Saturday morning despite an international campaign urging the government of Iran to stay her execution.
Human rights group Amnesty International said her execution was "deeply disappointing in the extreme", the BBC reports.
The US State Department and the British Foreign Office, both condemned the execution of Jabbari.
He further called on Iran to put a moratorium on all executions.
The report added that Iran's government news agency Tasnim said on Saturday that Jabbari, who was convicted of the 2007 fatal stabbing of Morteza Abdolali Sarbandi, was executed after her relatives failed to gain consent from the victim's family for a reprieve.
The Iranian, who was then 19 and worked as a decorator, had agreed to go to the former employee of the Iranian Intelligence Ministry's office to discuss a business deal.
She claimed that Sarbandi offered her a drink laced with drugs and tried to rape her after taking her to a rundown building in a remote location, following which she stabbed him with a small pocket knife and fled while he bled to death.
