حركة القوميين العرب
The PLF was founded by Ahmed Jibril and Shafiq al-Hout in 1959, with strong Syrian backing. In 1964, the PLF as a whole was one of the eight constituent groups that had originally formed the Palestinian Liberation Organization (PLO) which was under the chairmanship of Yasser Arafat. In 1967, the PLF merged with the Arab Nationalist Movement-affiliated Heroes of the Return ("abtal al-awda") and the Young Avengers, to form the Popular Front for the Liberation of Palestine (PFLP).
