Popular Front for the Liberation of Palestine

The Popular Front for the Liberation of Palestine (PFLP) (Arabic: الجبهة الشعبية لتحرير فلسطين, romanized: "al-Jabha al-Shabiyah li-Tahrir Filastin" or "al-Jabhah al-Shaʿbīyyah li-Taḥrīr Filasṭīn") is a secular Palestinian Marxist–Leninist and revolutionary socialist organization founded in 1967 by George Habash. It has consistently been the second-largest of the groups forming the Palestine Liberation Organization, the largest being Fatah.

Ahmad Sa'adat, who was sentenced in 2006 to 30 years in an Israeli prison, has served as General Secretary of the PFLP since 2001. The PFLP currently considers both the Fatah-led government in the West Bank and the Hamas government in the Gaza Strip illegal because elections to the Palestinian National Authority have not been held since 2006. As of 2015, the PFLP boycotts participation in the PLO Executive Committee and the Palestinian National Council.

The PFLP has generally taken a hard-line on Palestinian national aspirations, opposing the more moderate stance of Fatah. It does not recognize Israel, and promotes a one-state solution to the Israeli–Palestinian conflict, in a "democratic Palestine", where "Arabs and Jews would live without discrimination". The military wing of the PFLP is called the Abu Ali Mustapha Brigades.

The PFLP is well known for pioneering armed aircraft-hijackings in the late 1960s and early 1970s. According to PFLP Politburo member and former aircraft-hijacker Leila Khaled, the PFLP does not see suicide bombing as a form of resistance to occupation or as a strategic action or policy and no longer carries out such attacks. The PFLP has been designated a terrorist organization by the United States, Japan, Canada, and the European Union.
