The emir of al Qaeda, Ayman al Zawahiri, has released a new audio message addressing the infighting between jihadist groups in Syria. Zawahiri does not mention any specific groups or individuals by name, but much of his message is clearly aimed at the Islamic State of Iraq and the Sham (ISIS), a branch of al Qaeda that has been the main source of the internecine conflict.

Zawahiri addresses all of the jihadist factions fighting against Bashar al Assad’s regime, saying they are the best “hope” for establishing an Islamic state in the heart of the Levant, as well as “liberating Jerusalem,” according to a translation obtained by The Long War Journal.

Al Qaeda respects and admires “all of you,” Zawahiri says, addressing all of the factions as “brothers.” According to Zawahiri, al Qaeda’s leaders believe that the jihadists’ “brotherhood in Islam” is stronger than any temporary “organizational bonds.”
