ISRAEL REPORTED TO IMPERIL LAST P.L.O. EXIT
Israeli troops with tanks and armored personnel carriers reportedly moved into a village just five miles southeast of central Beirut tonight. If the troops consolidate their position, it could lead to the virtual encirclement of the capital and the Palestinian guerrilla forces there. Earlier, a brief cease-fire between Palestinian guerrillas and Israeli forces was shattered in a day of fierce fighting south of the city between Israeli troops and Palestinian guerrillas as well as repeated Israeli air strikes against West Beirut. The cease-fire was worked out Saturday by the Lebanese and United States Governments. If the Israelis hold their position in the village, Baabda, it would mark a major turning point in their seven-day invasion. It would put Israeli troops astride the strategic Beirut-Damascus highway at the entry of Beirut, choking off the last exit or entry route for the Palestinian guerrilla forces in the capital.
