List of attacks attributed to Abu Nidal
Abu Nidal (Sabri al-Banna) was regarded as the most dangerous of the Palestinian political leaders. Abu Nidal, whose pseudonym means "father of struggle" (Abu meaning father and Nidal, a secular term, meaning "struggle" or "effort" in Arabic) was primarily active in the 1970s and 1980s in the left wing of the Palestine Liberation Organization and later the secular/rejectionist front, and was accused by Western and Arab sources of acting as a mercenary for various Arab governments.
