On November 26, 2005 Fox was taken hostage along with three other members of the CPT team in Iraq. The captors threatened to kill all hostages unless the United States freed all Iraqi prisoners held in the US and Iraq by December 8, 2005. They later extended this deadline to December 10, 2005. On December 10, 2005, Katherine Fox issued a statement saying that she and her father believe the Iraqi people have legitimate concerns about the United States' presence in Iraq, but "these grievances, however, will not be resolved by taking my father's life."
