Our friend, Iranian-American consultant Siamak Namazi, has been in Tehran's Evin prison for six months. He has not been charged with a crime, and his detention has no legal basis. His health is at risk. He has been through a hunger strike and intense interrogations for the last nine months. Make no mistake: Siamak is innocent.

The motives behind these arrests have been lucidly explained, but news of detained Iranian Americans dies when there are no developments on the ground.

Baquer Namazi is 80 years old and his family says he's on medication for a heart condition.
