Democratic Front for the Liberation of Palestine
The 1969 congress also saw an ultra-leftist faction under Nayef Hawatmeh and Yasser Abd Rabbo split off as the Popular Democratic Front for the Liberation of Palestine (PDFLP), later to become the Democratic Front for the Liberation of Palestine (DFLP). During Habash's time as Secretary-General, the PFLP became known as one of the most radical and militant Palestinian factions and gained world notoriety after a string of aircraft hijackings and attacks against Israel affiliated companies as well as Israeli ambassadors in Europe mostly planned by Haddad. The PFLP's pioneering of modern international terror operations brought the group, and the Palestinian issue, onto newspaper front pages worldwide, but it also provoked intense criticism from other parts of the Palestine Liberation Organization.
