US Secretary of State Hillary Rodham Clinton is calling for the release of an Iranian-American journalist being held prisoner in Iran. Clinton was asked at a news conference Thursday what the US government was doing to secure the release of 31-year-old freelance journalist Roxana Saberi. She has reported for National Public Radio and other media. Clinton said she was concerned about Saberi, and that the State Department is working through Swiss authorities to request information from Teheran. They are seeking information on Saberi's well-being, whereabouts and what Clinton described as the charges made in her confinement. Clinton said the only acceptable outcome was for Saberi's release and return to her family in North Dakota.
