CAIRO – The announcement appeared to be an attempt by al Qaeda to put its house in order and reassert influence among rival Islamic groups that have turned against one another in Syria, where the groups have joined rebels in fighting to topple President Bashar Assad.
In past months, the Islamic State -- created by Abu Bakr al-Baghdadi, the head of al Qaeda's branch in Iraq -- has increasingly clashed with other hard-line Islamic factions, including assassinating commanders of rival groups with car bombs and shootings.
Al-Baghdadi created the Islamic State of Iraq and the Levant last year in defiance of orders from the terror network's leader, Ayman al-Zawahri, who at the time ordered him to remain the head of al Qaeda's branch in Iraq, while authorizing another group, Jabhat al-Nusra, or Nusra Front, to operate in Syria in al Qaeda's name. Al-Baghdadi went ahead and created the new group, becoming a powerful force in Syria's conflict.
In Monday's statement, al Qaeda's general command announced it has "no connection" with the Islamic State, underlined that the group "is not a branch of the al Qaeda organization," and said al Qaeda "is not responsible for its actions."
Al Qaeda did not condone the group's creation "and in fact ordered it to stop," the statement said.
It also condemned the infighting among Islamic groups, saying, "We distance ourselves from the sedition taking place among the mujahedeen factions (in Syria) and of the forbidden blood shed by any faction." It warned that mujahedeen, of holy warriors, must recognize the "enormity of the catastrophe" caused by "this sedition."
The authenticity of the statement could not independently be verified but it was posted on websites commonly used by al Qaeda.
The rebel-on-rebel fighting has added another bloody dimension to the Syrian crisis, which erupted in March 2011 as an uprising against President Bashar Assad's rule but later evolved into an armed insurgency and civil war.
The war provided fertile ground for militant Islamic groups and over time, the Islamic State and the Nusra Front emerged as the two main al Qaeda-linked groups until their falling out last spring. The Islamic State, meanwhile, largely eclipsed the Nusra Front in many parts of northern Syria.
Charles Lister of the Brookings Doha Center said the al-Qaeda statement reflected its "attempt to definitively re-assert some level of authority over the jihad in Syria."
It also showed al-Qaeda leadership's failure to take a genuinely commanding line in the rivalry between the Islamic State and the Nusra Front, and made it inevitable that al-Zawahri had to issue a decisive ruling with permanent consequences, said Lister.
