Grainy images show kidnapped activists are alive

Kidnappers of four kidnapped Christian peace activists threatened to kill them unless all Iraqi prisoners are released from Iraqi and US prisons, according to a tape broadcast today.

Al-Jazeera television aired a tape dated January 21 showing the four workers from the Chicago-based Christian Peacemaker activists, who disappeared on November 26. The previously unknown Swords of Righteousness Brigade claimed responsibility for the kidnapping.
