Outspoken Iranian blogger Mehdi Khazali has been released from jail for health reasons.
Khazali was serving a six-year prison sentence for acts against national security and spreading propaganda against the regime.
He was arrested about one month ago.
The official IRNA news agency quoted Khazali's lawyer as saying that the 48-year-old ophthalmologist was hospitalized after going on a hunger strike, and that the authorities had decided he was too ill to return to jail.
Khazali, the son of a prominent hard-line cleric, has been in and out of jail for the past several years.
Khazali has repeatedly criticized human rights abuses in Iran.
