The United States has condemned Iran's hanging of a woman found guilty of murdering an ex-intelligence officer who she said tried to rape her.
U.S. State Department spokeswoman Jen Psaki said Washington has "serious concerns" about the fairness of Reyhaneh Jabbari's trial and the circumstances surrounding her case.
Psaki said among the concerns were reports of confessions by Jabbari that were "made under severe duress."
Jabbari, 26, had been on death row for five years after being convicted of stabbing to death Morteza Abdolali Sarbandi in 2007.
She was hanged early on October 25 in Tehran.
The United Nations and international human rights groups have said her confession was made under intense pressure and threats by prosecutors.
The United Nations says more than 250 people have been executed in Iran so far this year.
