Tensions between al-Qaeda’s two branches fighting in Syria – Islamic State of Iraq and Syria (ISIS) and al-Nusra Front – are reaching a breaking point, despite efforts to resolve the dispute from the organization’s international leadership.
Despite their best attempts to keep the ongoing dispute between ISIS leader Abu Bakr al-Baghdadi and his Nusra counterpart, Abu Mohammed al-Golani, contained at the leadership level, al-Qaeda’s internal war in Syria is increasingly becoming public.
The disagreement between the two leaders first emerged when Baghdadi declared the formation of a single organization under his leadership that would cover both Iraq and Syria.
