(Baghdad, Iraq-AP, Mar. 14, 2006 12;18 PM) _ The interior minister said Tuesday authorities had foiled an al-Qaida plot that would have put hundreds of its men at critical guard posts around Baghdad's heavily fortified Green Zone, home to the U.S. and other foreign embassies as well as the Iraqi government.

A senior Defense Ministry official said the 421 al-Qaida fighters were actually recruited to storm the U.S. and British embassies and take hostages. Several ranking Defense Ministry officials have been jailed in the plot, the official said on condition of anonymity because of the sensitivity of the information.

Interior Minister Bayan Jabr, in an interview with The Associated Press, said the 421 al-Qaida recruits were one bureaucrat's signature away from acceptance into an Iraqi army battalion whose job is to control the gates and main squares in the Green Zone. The plot was discovered three weeks ago.
