JERUSALEM (AP) _ An explosion went off Tuesday on an Israeli bus in Jerusalem, and body parts were strewn across the pavement.

``I saw a great cloud and I saw people fleeing,'' said one witnesses, who would only give his first name, Doron. ``I looked down and saw the bus lying on its side in a very strange way and someone lying on the road nearby.''

The bus was headed from Jerusalem in the direction of the Jewish West Bank settlement of Maaleh Adumim.
