Iran's foreign minister says the Iranian scientist imprisoned in the US is now on his way back home.
Sirous Asgari had been pleading for weeks to be released from an immigration centre, after contracting COVID-19.
He has been in custody since 2017, while on trial for charges of fraud and selling state secrets.
Asgari was acquitted last month, but was transferred into immigration custody over an expired US visa.
