Iraqis survey a large crater caused by a U.S air strike in the restive town of Falluja July 1, 2004. At least four people were killed when U.S. forces attacked and destroyed what they said was a 'safe house' belonging to the Jordanian militant Washington views as its top guerrilla target in Iraq (news - web sites), Abu Musab al-Zarqawi. The assault was launched hours before ex-president Saddam Hussein (news - web sites) was due to appear before an Iraqi court on Thursday for formal arraignment. (Reuters)
