الجبهة الديمقراطية لتحرير فلسطين
Ibrahim became the General Secretary of OACL. OACL was closely allied with the Popular Democratic Front for the Liberation of Palestine led by Naif Hawatmeh, which had a similar background to the left-wing sector of the ANM. Hawatmeh had broken away from the ANM in 1969, setting up the PDFLP (later renamed as the Democratic Front for the Liberation of Palestine). "Al-Hurriya" was published from Beirut as the joint organ of PDFLP/DFLP and OACL until 1977, when it became the DFLP organ.
