An Israeli soldier guards the wreckage of a bus, which was destroyed by an explosion on the road near the Israeli Arab town of Umm al-Fahm March 20, 2002. A suspected Palestinian suicide bomber blew himself up on a bus in northern Israel killing four other people, as a U.S. envoy pressed on with efforts to bring a halt to 18 month of conflict.
