The al Qaeda operatives who will launch this attack are awaiting final orders. They remain in place in cities throughout the country. Many are masquerading as Christians and have adopted Christian names. The American people will be treated to a final audio message from Osama bin Laden which will be aired within the next two weeks.UPDATE: Jamestown is covering this now:
Recent reports indicating al-Qaeda's preparations for a nuclear attack in the United States by al-Qaeda's alleged nuclear expert, Adnan El-Shukrijumah, has prompted conflicting reactions among Islamists in the jihadi forums (Terrorism Focus, September 12; al-Arabiya, September 11). The jihadi forums described the possible nuclear attack, and they also discussed a separate plan by al-Qaeda to attack coalition forces in Afghanistan with 300 suicide bombers. This latter plan was labeled The Ramadan Invasion, a reference to Prophet Muhammad's first war with infidels that was called the Badr invasion that took place in the month of Ramadan. With regard to the nuclear plot, the debate revolved around whether Islam justifies killing innocent people with weapons of mass destruction. Other forums hailed the news of the possible nuclear attack by saying that "this is a good omen for all lovers of jihad" .
