JERUSALEM (AP) _ Israeli soldiers patrolling Israel's self-proclaimed security zone in southern Lebanon on Thursday shot and killed a guerrilla who apparently was planting mines on a road, the military command said.

Military sources who spoke on condition of anonymity said another guerrilla escaped when the Israelis opened fire early in the morning about four miles north of the Israeli border near the town of Bent Jbail.

The army said in a statement that a Soviet-made assault rifle and other weapons were found near the body. It did not say to which guerrilla group the gunman belonged.

The security zone is a six-to-10 mile strip north of the Israeli-Lebanese border that Israel created in June 1985 after withdrawing the bulk of its troops from Lebanon, ending a three-year occupation.

The security zone is patrolled by about 1,000 Israeli soldiers and the South Lebanon Army, a 1,200-member predominantly Christian militia which is trained and financed by Israel.
