The Abu Ali Mustapha Brigades is the armed wing of the Popular Front for the Liberation of Palestine (PFLP) in the Palestinian territories (the West Bank, Gaza and East Jerusalem).
Originally named the Red Eagles Brigades the Brigades were renamed in 2001 after Abu Ali Mustafa, the PFLP's leader who was killed by Israel in August 2001. They have been active with attacks on both military and civilian Israeli targets during the al-Aqsa Intifada.
On the 16 July 2007, Palestinian president Mahmoud Abbas requested of all Palestinian resistance groups to relinquish their weapons to the Palestinian Authority. Although several members of Fatah's armed wing Al-Aqsa Martyrs' Brigades complied, the Abu Ali Mustafa brigades rejected this, stating that they will not cease their resistance until the Israelis unoccupy all parts of the West Bank and the Gaza Strip.
