Coalition leaders said that foreign fighters were using the area to infiltrate into Iraq. In the city they would receive help from other anti-Iraqi forces. From the city foreigners would spread around Iraq. They were said to be part of a terror network led by Abu Musab al-Zarqawi.[1]
The operation was designed to root out anti-Iraqi and anti-coalition forces and destroying some of their support system. In clearing out the city coalition forces found four Iraqi hostages held in a bunker in the center of the city.
