The report about the delayed release of Sarah Shourd has not appeared on official news agencies or state television and could not be confirmed.
ILNA quotes Tehran chief prosecutor Abbas Jafari Dolatabadi as saying Friday that “because the judicial procedures have not been done, the release of the American suspect … has been canceled.”
Iranian officials had announced that they would free Shourd Saturday.
Shourd and two friends were arrested along the Iran-Iraq border in July 2009. Iran has accused them of illegal border crossing and spying. Their families say they were hiking and that if they crossed the border, they did so unwittingly.
