Meanwhile, in Iraq

Just as you expected....

Fighting has broken out in the holy city of Najaf.

The fighting around the coalition base began after Sadr's forces discovered that U.S. forces moved into the building earlier in the day, replacing a small force of Spanish troops who moved out as part of that country's unilateral withdrawal from Iraq. Militiamen described the arrival of the U.S. troops as discreet, with soldiers coming and going through a rear entrance of the building, built as an administrative annex to a hospital named for Sadr's late father, a revered ayatollah.

The initial firefight involved more than an hour of heavy rifle and machine-gun fire as well as mortars, witnesses said. Militia members fell back after U.S. attack helicopters arrived, but they appeared to be regrouping and adding reinforcements.
