NEW YORK (AP) - Najibullah Zazi is due in a Denver court again today.
The Afghan immigrant is accused of plotting to use simple materials bought at beauty stores to build bombs for al-Qaida.
Prosecutors say they don't know where the attacks were supposed to take place, but Attorney General Eric Holder says he believes "any imminent threat arising from this case has been disrupted."
Authorities call the alleged plot one of the most significant terror threats to the U.S. since 9/11.
Most chilling in the 12-page memorandum outlining the alleged conspiracy was the repeated phrase "and others," evidence of a possible al-Qaida cell plotting a homemade bomb attack on U.S. soil.
A law enforcement official tells The Associated Press that Zazi had associates in New York who were in on the plot.
