From the AP:

In one of the bloodiest days in weeks for the U.S. military, five troops died when a bomb exploded under their military vehicle west of Baghdad on Wednesday. At least four foreign nationals, including one American, were killed in a separate attack and some of the bodies were burned, beaten and hanged from a bridge. The explosive device that killed the American troops blew up when their vehicle ran over it, U.S. Army Col. Jill Morgenthaler said in Baghdad. The attack happened in Anbar province, which encompasses Fallujah, Ramadi and other towns where anti-U.S. insurgents are active.

In the second incident, the Iraqis dragged the bloody bodies through the streets:

It was reminiscent of the 1993 scene in Somalia, when a mob dragged the corpse of a U.S. soldier through the streets of Mogadishu, eventually leading to the American withdrawal from the African nation.
