This undated photo provided Tuesday, March 3, 2009 by the National Press Photographers Association shows U.S. journalist Roxana Saberi. Iran's judiciary spokesman says Saberi, who was detained about a month ago, is being held in a prison north of the capital, Tehran. Ali Reza Jamshidi says 31-year-old Saberi is being held in Evin prison on a court order. He refused to provide further details in a press conference Tuesday March 3, 2009. Iran's Foreign Ministry Spokesman Hasan Qashqavi said Monday that Saberi was engaged in "illegal" activities because she continued working in Iran after the government revoked her press credentials in 2006. Saberi's father, Reza, has said his daughter told him in a Feb. 10 phone call that she was detained after buying a bottle of wine. Reza Saberi, who lives in Fargo, N.D. , said he has not heard from her since.
