Kidnapping, and in some cases beheadings, have emerged as another insurgent tactic since April 2004. Foreign civilians have borne the brunt of the kidnappings, although U.S. military personnel have also been targeted. After kidnapping the victim, the insurgents typically make some sort of demand of the government of the hostage's nation and give a time limit for the demand to be carried out, often 72 hours. Beheading is often threatened if the government fails to heed the wishes of the hostage takers. Several individuals, including an American civilian (Nicholas Berg) and a South Korean (Kim Sun-il), among others, have been beheaded. In many cases, tapes of the beheadings are distributed for propaganda purposes. However, 80% of hostages taken by insurgents have been peacefully released. Jill Carroll, a journalist for the Christian Science Monitor, was kidnapped in early 2006, and although later let go, her Iraqi interpreter was killed.
