Jill Carroll, reporter for the Christian Science Monitor, was shown on a video today on al-Jazeera. The audio was not broadcast and there was no mention of the terrorist group that took her hostage. They have threatened to kill her if all Iraqi females in prison are not released by the US in 72 hours.

Jill Carroll was taken hostage January 8, 2005 on her way to a meeting with head of the Iraqi Consensus Front, Adnan al-Dulaimi. Her interpreter Alin Ghazi Jack was killed in the hostage taking.

The abductors of U.S. journalist Jill Carroll have threatened to kill her if the United States does not free Iraqi women prisoners within 72 hours, Al Jazeera television said on Tuesday.

...

The station did not say which group had claimed to kidnap her.

Carroll, a 28-year-old American journalist working for The Christian Science Monitor, was abducted earlier this month by unknown kidnappers who also killed her Iraqi interpreter.

Reuters also says that Carroll is the 31st reporter taken hostage in Iraq. Though some out there would call some of those hostage takings staged or suspicious.
