Najibullah Zazi, a 24-year-old shuttle driver at the Denver airport, was indicted in New York on charges of conspiracy to use weapons of mass destruction. Investigators said they found bomb-making instructions on his computer's hard drive and said Zazi used a hotel room in Colorado to try to cook up explosives a few weeks ago before a trip to New York.
The extent of Zazi's ties to al-Qaida was unclear, but if the allegations prove true, this could be the first operating al-Qaida cell to be uncovered inside the U.S. since the Sept. 11, 2001, attacks. Over the past few days, talk of the possible plot set off the most intense flurry of national terrorism warnings since the aftermath of 9/11.
Prosecutors said they have yet to establish exactly when and where the Zazi attacks were supposed to take place. But Attorney General Eric Holder said in Washington, "We believe any imminent threat arising from this case has been disrupted."
Zazi was arrested in Denver last weekend and was charged along with his father and a New York City imam with lying to investigators. Authorities said in the past few days that they feared Zazi and others might have been planning to detonate homemade bombs on New York trains, and warnings went out to transit systems, stadiums and hotels nationwide.
