Palestinian guerrilla activity against Israel in 1975…

Palestinian guerrilla activity against Israel in 1975 is largely confined to the southern Lebanese border area, where it provokes heavy Israeli reprisals from air, land, and sea against Palestinian refugee camps that the Israelis allege are used as guerrilla bases.

Israeli raids, however, are overshadowed by the civil strife in Lebanon that has developed along Muslim-Christian lines.

The PLO had initially tried to stay out of the fighting, but by the end of 1975 groups within the overall organization, particularly the "rejection front" groups, are being drawn into an alliance with the Muslim side fighting against the Christians.
