Rivalry between jihadist groups fighting in Syria has sharply divided global militant ranks once loosely allied under Al Qaeda, sparking infighting which experts say has hampered efforts to topple President Bashar al-Assad.

And while senior leaders of Al Qaeda were all but above question under founder Osama bin Laden, the conflict has gone so far that even his replacement Ayman al-Zawahri has come in for fierce criticism on jihadist forums online.

Powerful rebel groups in Syria, including Al Qaeda’s designated local affiliate Al Nusra Front, have been locked in fierce fighting with the Islamic State of Iraq and the Levant (ISIL), with thousands of people killed since January.

Jihadists were initially welcomed by other rebels battling to topple Assad since 2011.

But allegations of brutality towards civilians and rival fighters sparked a backlash and even accusations that they served Assad’s interests.

In a sign of how sharp the divisions have become, ISIL spokesman Abu Mohamed al-Adnani has accused Al Qaeda leaders of betraying the jihadist cause.

“Al Qaeda today is no longer a base of jihad,” Adnani said in a statement posted on jihadist forums, playing off the militant group’s name, which means “the base” in Arabic.

“Its leadership has become a hammer to break the project of the Islamic State,” Adnani said, adding that “the leaders of Al Qaeda have deviated from the correct path”.

“They have divided the ranks of the mujahedeen in every place.”

In an interview with a Qaeda-run media outlet released by the SITE monitoring service yesterday and dated between February and April, Zawahri called for unity and suggested the Assad regime had penetrated jihadist ranks and sowed sedition.

“If I command you to fight your mujahideen brothers, do not obey me. If I command you to blow yourself up among your mujahideen brothers, do not obey me,” he said.

Online, the clash among jihadists has seen criticism of Zawahri from around the Islamic world, though others have defended the Al Qaeda chief.

“Zawahri has fallen... We will not listen to him anymore. To the dustbin of history, oh Al Qaeda,” tweeted ISIL supporter Munassar al-Mumineen.

Ahmed, another Twitter user, attacked Zawahri as “old” and called him “the Prince of the Khawarij”—those who have left the proper path of jihad.

Charles Lister, a visiting fellow at the Brookings Doha Centre, said the dispute is ultimately over leadership of the jihadist movement in Syria and internationally.

“This continuing battle for influence between Al Nusra and ISIL has the potential to cause shock waves across the international jihadist community.

“The conflict in Syria has provided an enormous opportunity for jihadist groups, and with such a significant opportunity comes the possibility of divisions,” he added.

Alan Fraser, a Middle East and North Africa specialist with British risk consultancy AKE Group, said disputes among jihadists have happened before, including within Al Qaeda itself.

“Jihadist groups have always been prone to division and infighting, as there is generally a lot more at stake than just ideological issues,” he said.

“There have always been tensions between and within groups over the extent of their extremism and the lengths they will go to seek funding and to impose their beliefs on local populations.”

Inside Syria, splits between jihadist groups ultimately play into Assad’s hands.

“It has played a significant role in dividing the opposition movement, as well as dividing opinion and the degree of support among those who had previously supported the uprising,” Fraser said.
