Saeed Abedini, an American pastor imprisoned in Iran for his faith, is facing life threatening conditions after a recent prison transfer, the America Center for Law and Justice reports.
Saeed's family says he has been moved from the brutal Evin Prison to Rajai Shahr Prison, known to be an even more dangerous jail.
"Going to Karaj (the Iranian city where Rajai Shahr is located) is a severe punishment," Loes Bijnen, a Dutch diplomat from the embassy in Tehran, described the jail in a 2005 report.
"Once in there, one stops to be a human being," she wrote. "One is put out of sight, even of human rights activists and the press. Murders or unexplained deaths are a regular occurrence."
According to the ACLJ, Saeed is in a ward with those convicted for crimes like rape and murder.
Family members tried to visit the pastor Monday but were told he isn't allowed to have visitors in the new prison.
"The transfer to this prison is a deeply disturbing development and can only be viewed as a move that puts Pastor Saeed's life directly at risk," ACLJ Executive Director Jordan Sekulow warned.
While there is broad bi-partisan support for a Senate resolution calling for Saeed's release, Sekulow says it's crucial President Barack Obama step in "directly and forcefully" to save his life.
***Urge the president to push for Pastor Saeed's release by signing the ACLJ's petition.
Meanwhile, another Christian imprisoned in Iran, Mostafa Bordbar, has been set free just three months into his 10-year sentence.
Bordbar, 27, was celebrating Christmas last year when he was arrested. He faced several charges, including intending to commit crimes against Iranian nation security.
An appeals court overturned his conviction last month, leading to his release.
