A suicide car bomber killed three Fijian soldiers from the U.N. peacekeeping force and four civilians at a U.N. roadblock in southern Lebanon. The driver, who also died, was stopped six miles south of Tyre, for a routine check. Two other Fijian soldiers, two other civilians and a member of an Israeli-backed militia were wounded. A U.N. spokesman said he did not know whether the bomber intended to kill U.N. troops or members of the Israeli-backed South Lebanon Army militia, who manned a nearby roadblock. The United Nations Interim Force in Lebanon and the South Lebanon Army militia have frequently been attacked by Muslim guerrillas in south Lebanon.
