U.S. troops in Fallujah have found a safe house which they say contains evidence linked to wanted militant Abu Musab al-Zarqawi.

U.S. Lieutenant General John Sattler Thursday did not confirm the find, but he said coalition troops had found a number of insurgent headquarters in the city.

Embedded reporters in Fallujah say troops searching the safe house property found photographs, notes, ammunition and letters thought to be from al-Zarqawi. Videotape shot by an American news crew also showed a mural pledging allegiance to the al Qaida terrorist network.

Several bodies lay outside the house, and soldiers found an American-made truck wired with explosives nearby.

U.S. and Iraqi officials have said the terrorist leader probably fled Fallujah ahead of the recent assault.
