A top U.S. military commander in Iraq says insurgents in the city of Fallujah are moving "blindly" through the city without the ability to communicate or coordinate attacks.
Lieutenant-General John Sattler said on Wednesday that many insurgents fled ahead of the offensive, but the ones who have remained will be hunted down and killed.
American commanders in Iraq said earlier that U.S. and Iraqi troops control about 70 percent of the city, including key bridges and buildings.
Meanwhile, an Iraqi military spokesman says his troops have found houses in northern Fallujah used by kidnappers to keep and kill hostages.
And insurgents claimed to have kidnapped 20 Iraqi national guardsmen in Fallujah. In a video, the men were dressed in camouflage uniforms, but did not face the camera. The authenticity of the claim has not been verified.
