Carroll's captors have said they would kill her if the United States did not meet their demands by 26 February. The kidnappers are from a group calling itself the Revenge Brigades. They have publicly demanded the release all female prisoners in Iraq.
Carroll is a 28-year-old freelance journalist who was working on an assignment for "The Christian Science Monitor" newspaper when she was kidnapped on 7 January in Baghdad.
She was last seen in a videotape broadcast on 9 February by the private Kuwaiti television station Al-R'ay.
Al-R'ay's owner Jassem Boudai says the kidnappers provided more specific conditions for Carroll's release. But he has refused to reveal those conditions.
