French-Iranian academic Fariba Adelkhah has been temporarily released from prison with an electronic ankle bracelet, her lawyer has said, reports the BBC.
She is now with her family in the Iranian capital, Tehran, Saeid Dehghan said.
He hoped this temporary release would become final, he told the AFP news agency.
The academic was given a six-year jail term on national security charges in May.
She received a five-year term for conspiring against national security and one year for propaganda.
