Saeed Abedini, the American pastor imprisoned for his faith in Iran, is now in solitary confinement.
Family members have confirmed Pastor Saeed was sent there with nine other prisoners.
According to the American Center for Law and Justice, the move comes after Saeed and others from Ward 350 petitioned Evin Prison about its inhumane conditions.
Since his imprisonment last fall, Saeed has sustained internal bleeding and now there are fears his kidneys are failing.
"Saeed had previously told his family that when he was in solitary confinement in the past, that was the hardest time in his life," Pastor Saeed's wife, Naghmeh, said, "That every hour was like one year and that he was losing his memory and his health was deteriorating quickly."
"Please pray for his health and healing," she said. "Pray for his release. Pray that the Lord would use this for His Glory and salvation of many."
