Iranian authorities have hanged a 26-year-old woman for the murder of a former intelligence official.
Iran's official IRNA news agency quoted the Tehran prosecutor's office as saying Reyhaneh Jabbari was hanged at dawn on October 25.
A Facebook page, "Save Reyhaneh Jabbari From Execution In Iran," that campaigned for her release confirmed her execution.
Amnesty International said in a October 24 statement that Jabbari, an interior designer, was due to be executed for the 2007 stabbing of Morteza Abdolali Sarbandi.
A UN human rights monitor has said the killing of Sarbandi was self-defense after he tried to sexually assault Jabbari, and that her 2009 trial and conviction was flawed.
The United Nations says more than 250 people have been executed in Iran in 2014.
