The PLO took advantage of its control of southern Lebanon in order to launch Katyusha rocket attacks at Galilee villages and execute terror attacks on the northern border . At the beginning of the 1970s the Palestinian terror organizations , headed by the PLO and the Popular Front for the Liberation of Palestine waged an international terror campaign against Israelis , primarily in Europe . In an attempt to publicize the Palestinian cause , frustrated Palestinian guerrilla groups in Lebanon attacked Israeli civilian ' targets ' like schools , buses and apartment blocks , with occasional attacks abroad — for example , at embassies or airports — and with the hijacking of airliners . The peak of the Palestinian terrorism wave against Israelis occurred in 1972 and took form in several acts of terrorism , most prominently the Sabena Flight 572 hijacking , the Lod Airport massacre and the Munich massacre
