NEW YORK AP – Terror suspect Najibullah Zazi plotted for more than a year to detonate homemade bombs in the United States, had recently bought bomb-making supplies from beauty supply stores and was looking for “urgent” help in the past two weeks to make explosives, an indictment charged Thursday.

Zazi, arrested in Denver last weekend on a count of lying to terrorism investigators, was charged in New York with using conspiracy to use weapons of mass destruction.
