Sweeps and raids through the Moslem south has revealed evidence of a network of mobile terrorist training camps. It appears that the instructors have a fairly standard curriculum, which teaches how to build nine different types of bombs, using  eight chemical recipes for preparing explosives. Trainees are taught how to place the bombs, and set them off for maximum effect. The bombs produced by the graduates of these courses have killed about 116 people in the last two years. Many of the instructors are from Indonesia, or Arab countries. The number of trainees is not great, perhaps a few dozen.
