The uprising ...defended its homeland with its rifles
Fatah al-Intifada (Arabic: فتح الانتفاضة Fatah Uprising) is a Palestinian militant faction founded by Col. Said al-Muragha, better known as Abu Musa. The group is often referred to as the Abu Musa Faction. Officially it refers to itself as the Palestinian National Liberation Movement - "Fatah" ("حركة التحرير الوطني الفلسطيني - "فتح), the identical name of the major Fatah movement. Fatah al-Intifada is not part of the Palestine Liberation Organization (PLO).
Rupture with PLO
Originally part of Fatah, Fatah al-Intifada broke away from the organization in 1983, during the PLO's participation in the Lebanese Civil War. The split was due to differences between Abu Musa and Yassir Arafat over a number of issues, including military decisions and corruption. Fatah al-Intifada was formed with Syrian support and quickly attracted a number of Palestinian guerrillas disillusioned with Arafat's role in Fatah and the Palestine Liberation Organization (PLO). There was also a political dimension: the organization took a more leftist view than the generally apolitical Fatah, and used socialist phraseology. Abu Musa is known to have advocated the view that the Lebanese Civil War was not a sectarian conflict, but a form of class war. Syria provided extensive backing as the Abu Musa forces attacked Arafat loyalists in Fatah, while several radical PLO organizations in the Rejectionist Front stayed on the sidelines. The fighting led to heavy losses on both sides, and helped Syria extend its influence into Palestinian-held areas of Lebanon.
