From Holden:

The Iraqi insurgency is turning it up a notch by attacking within the Green Zone.

An improvised bomb was found in a restaurant in Baghdad’s heavily fortified Green Zone, home of the U.S. Embassy and key government offices, American officials said Thursday.

The device was found around midday Tuesday at the Green Zone Cafe, a popular hangout for Westerners living and working in the compound. A U.S. military ordnance detachment safely disarmed it, U.S. officials said.

Mortar rounds are often fired at the compound and there have been a number of deadly car bombings at its gates. But it was believed to be the first time that an explosive devise was planted inside the Green Zone.
