A US journalist detained about a month ago is being held in a prison north of Teheran, Iran's judiciary spokesman said Tuesday.
Ali Reza Jamshidi said Roxana Saberi, 31, was being held in Evin prison on a court order. He refused to provide further details in Tuesday's press conference.
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. He said he has not heard from her since.
