Coalition forces raid militia's stronghold

US and Iraqi forces swept into Baghdad’s Sadr City Shiite slum in an early morning raid today, killing four Iraqis, wounding eight and detaining five, police said.

It was the fourth coalition attack in six days on the slum, which is home to the Mahdi Army, the militia loyal to radical anti-American Shiite cleric Muqtada al-Sadr and suspected of having kidnapped an American soldier last month and taken scores of Iraqi hostages during an attack on a government building in Baghdad on November 14.
