From the NYT - and, yes, this strikes me as a more important story than some cranky old bigot on the radio:
The Convention Center is one of the most heavily guarded buildings inside the Green Zone, a four-square-mile area surrounded by blast walls and concertina wire that houses the offices of the Iraqi government and the American embassy.
The blast followed the destruction of the al-Sarafiya brudge in Baghdad by hours. Message: Nowhere is safe. Surge or no surge: this country is in collapse.

A suicide truck bomb exploded on the busy bridge, killing at least 10 people, cutting the bridge in two. The bridge connects the Sunni Waziriyah and the Shiite Utafiyah neighbourhoods.
