I have no idea what Iran means by “written work,” but is sure sounds like a forced confession to me:
Iran on Sunday said it had concluded the investigation into two US-Iranian academics detained for the past three months on charges of harming national security.
Tehran’s deputy prosecutor Hassan Hadad added that Middle East expert Haleh Esfandiari and urban planner Kian Tajbakhsh now had to do “written work” before a decision could be taken about their fate.
Esfandiari and Tajbakhsh have been held in Tehran in Evin prison since their arrest in May, in a case that has further strained ties with between Iran and its arch-foe the United States.
“The investigation into Haleh Esfandiari and Kian Tajbakhsh has ended,” Hadad, Tehran’s deputy prosecutor responsible for security crimes, told the state-run IRNA news agency in an interview.
“The two must now do a series of written work. After this, a decision on them will be taken,” he added.
Hadad gave no further information on what this “written work” involved.
