How extensive are those sleeper cells? This from The Herald, with thanks to Mohamed Ibn Guadi:
Islamic terror commandos are being infiltrated into the US in preparation for “an American jihad” from within, according to intelligence sources.
Dozens of radicals trained in camps in western Pakistan and Kashmir are already believed to have slipped into the country and been absorbed in sleeper cells in unsuspecting Muslim communities as the vanguard of a holy army estimated to be several hundred strong.
An FBI spokesman said al Qaeda and allied organisations were thought to be operating in 40 American states, awaiting orders for terror attacks.
