Edit, 22 November:
In a note on Karroubis latest letter, the blog Enduring America today had this interesting note about Saeeda in brackets:
"The claims that Pouraghai had been raped and killed by security forces are now discounted. Some believe the case was “manufactured” by the regime so it would discredit the opposition when the falsehood emerged."
It seems this story may have been planted by the regime.
