Over several nights in September, some 10,000 men, women and children fled areas under Islamic State control, hurrying through fields in northern Syria and risking fire from government troops to reach a province held by an al-Qaida-linked group.
For an untold number of battle-hardened jihadis fleeing with the civilians, the escape to Idlib province marked a homecoming of sorts, an opportunity to continue waging war alongside an extremist group that shares much of the Islamic State’s ideology — and has benefited from its prolonged downfall.
While the U.S.-led coalition and Russian-backed Syrian troops have been focused on driving IS from the country’s east, an al-Qaida-linked insurgent coalition known as the Levant Liberation Committee has consolidated its control over Idlib, and may be looking to return to Osama bin Laden’s strategy of attacking the West.
Syrian activists with contacts in the area say members of the Levant Liberation Committee vouched for fleeing IS fighters they had known before the two groups split four years ago and allowed them to join, while others were sent to jail. The activists spoke on condition of anonymity because they still visit the area and fear reprisals from the jihadis.
IS has lost nearly all the territory it once controlled in Syria and Iraq, including the northern Iraqi city of Mosul — the largest it ever held — and the northern Syrian city of Raqqa, which once served as its de facto capital. Tens of thousands of its fighters have been killed on the battlefield, but an untold number have escaped. As it gradually disintegrates, theological splits have also emerged within the organization, including the rise of a faction that blames its leader, Abu Bakr al-Baghdadi, for the setbacks.
“Al-Qaida will welcome ISIS members with open arms, those are battled-hardened with potent field experience,” said Fawaz Gerges, a professor at the London School of Economics and the author of “ISIS: A History.”
ISIS is an alternative acronym for the Islamic State group.
The two groups both sprang from al-Qaida in Iraq, which emerged in the years after the 2003 U.S.-led invasion, but split over ideology and leadership in 2013 and battled each other across northern Syria. Earlier this month, IS attacked the Levant Liberation Committee again, in what was seen as a revenge attack after the defections.
While IS went on to carve out a proto-state in large parts of Syria and Iraq and declared an Islamic caliphate in 2014, the al-Qaida militants allied themselves with other Syrian insurgent groups and cultivated grass-roots support by providing aid and other services to civilians. They remained focused on the war against Syrian President Bashar Assad’s forces, although they’ve also crushed several small U.S.-backed rebel factions.
But despite formally severing ties with al-Qaida last year and repeatedly changing its name, the group is still widely seen as a local affiliate of the global network that carried out the Sept. 11 attacks. Brett McGurk, the top U.S. envoy for the coalition battling the Islamic State group, has said Idlib is the largest al-Qaida haven since bin Laden’s days in Afghanistan.
“I worry that al-Qaida has taken advantage of the past three or four years to very quietly rebuild while ISIS has preoccupied our attention,” said Bruce Hoffman, head of Georgetown University’s security studies program and author of “Inside Terrorism.”
“This is in al-Qaida’s DNA, to either absorb, wait out or forcibly deal with any of their rivals so that they’re the last man standing.” The growth of the Levant Liberation Committee in the past year “has astonished me,” he added.
Two Iraqi intelligence officials told The Associated Press in Baghdad that bin Laden’s successor, Ayman al-Zawahri, sent an envoy to Syria to convince IS fighters to defect and join his group. The officials, who spoke on condition of anonymity because they were not authorized to brief reporters, said this might have been the reason behind an audiotape released by IS leader Abu Bakr al-Baghdadi on Sept. 28, in which he ordered his fighters not to “retreat, run away, negotiate or surrender.”
While al-Qaida may yet regain the mantle of worldwide jihad, it could also come under increasing threat in its bastion in northwestern Syria, as the forces arrayed against IS shift their focus to a new potentially worldwide threat.
“The honeymoon period for al-Qaida, in which the so-called Islamic State absorbed most of the counterterrorism focus while al-Qaida’s affiliates grew stronger, is coming to an end,” according to an analysis by the Soufan Group security consultancy.
“It now appears Zawahiri is seeking to consolidate the terror network and return the group to its heyday as the vanguard of a global movement,” it added. That could place the militants in the crosshairs of the international coalition.
Turkey launched a limited military operation in Idlib last week aimed at imposing a “de-escalation zone,” one of several set up across Syria under an agreement between Turkey, Iran and Russia. The Turkish troops have yet to confront al-Qaida, but that could change if it comes to be seen as a regional or international threat.
Meanwhile, Assad’s forces, fresh from victories against IS in eastern Syria, may switch their focus to Idlib, the largest remaining insurgent bastion in the country. Russia, which has been waging an air campaign in support of Assad since 2015, struck an al-Qaida gathering in Idlib earlier this month and claimed to have killed several militant commanders.
The U.S.-led coalition has targeted al-Qaida militants on several occasions in recent years, aiming to disrupt what U.S. officials say is a secretive cell known as the Khorasan group that is planning external attacks. A U.S. airstrike killed al-Qaida’s second in command, former bin Laden aide Abu al-Kheir al-Masri, in Syria earlier this year.
