Hundreds of families have signed up to join a new community dubbed the Citadel, an armed and 'defensible' fortress city where their freedoms and liberty will be fiercely protected.

Organisers have outlined plans for a community of 3,500 to 7,000 families of 'patriotic' Americans in western Idaho living and more than 200 have already signed up through their website.

The group has already purchased 20 acres in the area where they intend to build an arms factory which will be used to fund the project.
