NYC subway terror plot revealed in new book...

"Exclusive Book Excerpt: How an Al-Qaeda Cell Planned a Poison-gas Attack on the
N.Y. Subway"

Ali revealed that Ayeri had visited Ayman Zawahiri in January
2003, to inform him of a plot to attack the New York City subway system using
cyanide gas. Several mubtakkars were to be placed in subway cars and other
strategic locations. This was not simply a proposal; the plot was well under
way. In fact, zero-hour was only 45 days away. But then, for reasons still
debated by U.S. intelligence officials, Zawahiri called off the attack. "Ali did
not know the precise explanation why. He just knew that Zawahiri had called them
off."
The news left administration officials gathered in the White House
with more questions than answers. Why was Ali cooperating? Why had Zawahiri
called off the strike? Were the operatives planning to carry out the attack
still in New York? "The CIA analysts attempted answers. Many of the questions
were simply unanswerable."
