The expulsion of large numbers of Palestinian guerrillas from Jordan in late 1970 and 1971, as a result of severe clashes between the Jordanian army and the PLO, had serious repercussions for Lebanon, however. Many of the guerrillas entered Lebanon, seeing it as the most suitable base for launching raids against Israel. The guerrillas tended to ally themselves with existing leftist Lebanese organizations or to form various new leftist groups that received support from the Lebanese Muslim community and caused further splintering in the Lebanese body politic. Clashes between the Palestinians and Lebanese right-wing groups, as well as demonstrations on behalf of the guerrillas, occurred during the latter half of 1971. PLO head Arafat held discussions with leading Lebanese government figures, who sought to establish acceptable limits of guerrilla activity in Lebanon under the 1969 Cairo Agreement.
