"AMERICA is to spend £1billion on an embassy in Baghdad "more secure than the Pentagon". Plans for the hi-tech complex are being kept secret because of the terrorist threat in Iraq. The exact location is not being released until later this year but it is likely to be built in the heavily fortified Green Zone area where the Iraqi government and US military command is based. The embassy will be guarded by 15ft blast walls and ground-to-air missiles and the main building will have bunkers for use during air offensives. The grounds will include as many as 300 houses for consular and military officials. And a large-scale barracks will be built for Marines who will protect what will be Washington's biggest and most secure overseas building."
