Iraq, North Korea May Possess Smallpox "U.S. intelligence believes four nations other than the United States -- Iraq, North Korea, Russia and France -- probably possess hidden samples of the smallpox virus, a U.S. official said. Al-Qaeda is also believed to have sought samples of smallpox for weaponization, but U.S. officials don't believe the terror network is capable of mounting an attack with smallpox. Evidence recovered in Afghanistan pointed to Osama bin Laden's interest in the disease, the U.S. official said Monday, speaking on condition of anonymity."
