Palestinian guerrillas reinforced their cratered and battered positions near Beirut on Saturday, less than 24 hours after Israel carried out a punitive land, sea and air offensive against them.

A spokesman for Palestinian group whose positions south of the Lebanese capital were rocketed for eight hours by Israeli helicopters and gunboats on Friday said the guerrillas were on high alert.About 200 Israeli commandos took part in the assaults under a curtain of rocketfire, which lashed bases of the Popular Front for the Liberation of Palestine-General Command (PFLP-GC) in the villages of Haret al-Naameh, Aramoun, Shemlan, Baawarta, and Abey, southeast of Beirut.
