ISIS internal docs show struggle to retain fighters, cut costs
WASHINGTON (CNN) -- ISIS is facing cash and manpower shortages, the deputy commander of the counter-ISIS coalition said Tuesday. His statement was reinforced by newly obtained internal ISIS documents. The cache shows the group struggling for funds -- some of which are used to pay for sex slaves -- and calling on fighters to use less electricity and stop driving official cars for personal use. The fighters, meanwhile, seem to be suffering low morale, in some case seeking doctors' notes to avoid serving on the frontlines.
