Al Qaida-backed militants Saturday stormed the base of the most prominent civilian commander in the U.S.-backed Syrian rebel force, forcing him and his fighters to flee into hiding in the Jebal al Zawiya mountains of northern Syria.
Jamal Maarouf, a contractor in private life, became internationally known for leading the successful offensive in January that forced the Islamic State from most of two northern provinces. His ouster from his own village was an enormous setback for him, the rebel forces and his international backers.
Even more ominous was that that Islamic State, now far stronger and claiming to run a caliphate in Syria and Iraq, reportedly joined the Nusra Front in the attack on the village of Deir Sinbul.
The Syrian Observatory for Human Rights, a London-based opposition monitoring group, said Islamic State fighters had arrived from the east of Syria to join the al-Qaida affiliate in the fight against Maarouf’s Revolutionaries of Syria Front.
Never miss a local story.
And Mahmoud al Ugal, a commander in Marouf’s force, said the militant fighters had deployed at least 20 heavy machine guns. He said the Nusra fighters used tanks, mortars and Chechen snipers in the battle for Deir Sinbul, Maarouf’s home town.
Ugal said the fighters had traveled by convoy across the Syrian desert, an assertion that coincided with information McClatchy obtained from another Syrian rebel commander early in the week as the convoy was reportedly setting out. McClatchy contacted both the U.S. Central Command and Pentagon officials for comment on the report, but neither could confirm it.
If Islamic State fighters did join Nusra in the attack, it will have major repercussions for the war in Syria, for the two groups have been divided since April 2013, when Abu Bakr al Baghdadi, the Iraq-based leader, announced the creation of Islamic State. Nusra had supported the rebel war against Assad until very recently and also was at war with Islamic State.
Islamic State’s fighters are mostly foreign volunteers, while Nusra’s forces consist largely of Syrian fighters.
The latest developments also raise the question whether the U.S., which daily bombards jihadist positions in a small Kurdish enclave in northeastern Syria, was monitoring the other fronts in the Syrian war where Islamic State is active.
Saturday’s fighting also confirmed that rebel forces, led by commanders such as Maarouf, who have been vetted by the CIA, now are fighting a three-front war against the regime, the Islamic State and Nusra, with only limited U.S. support.
Rebel leaders earlier this week pleaded in vain for U.S. help. “The war is widening now, and we are defending our existence,” Gen. Muhammad Hallak of the Syrian Revolutionary Front said Wednesday. He warned that if the U.S.-led coalition of western and Arab countries “lets us down, then we will withdraw our forces from the front with the Islamic State and the regime, and work only to save ourselves.” Hallak, like Maarouf, has been vetted by the CIA and receives covert U.S. military aid.
The battle over Jebel al-Zawiya, the first major stronghold controlled by the Syrian rebels fighting the Assad regime, began just a week ago. By Saturday Nusra had already captured a dozen rebel-controlled villages before reaching Deir Sinbul. In a statement on Twitter, Nusra accused Maarouf of “corruption” and “straying from the path of the revolution.”
Maarouf, in a video released on YouTube Saturday, said the Islamist forces had been attacking civilians and he had withdrawn his forces from his village into the mountains in order to save civilian lives.
The rise of Nusra, and its apparent collaboration with Islamic State, casts a harsh light on the U.S. approach to Syria, which has been to bomb Islamic State, and ignore the internal conflict between rebel forces and the Assad regime, which gave rise to the radical Islamists.
As moderate Syrian allies have lost ground, Nusra and Islamic State have been the major gainers. Another commander in the rebel force said the situation is the worst since the creation of the Free Syrian Army, an umbrella organization uniting locally based factions throughout the country.
He said as a result of the U.S.-led international coalition’s decision to bomb the two Islamist groups but do nothing to stop the Syrian government’s assault on Syrian civilians, rebel fighters are reluctant to confront Nusra. The official could not be quoted by name because he was not authorized to speak to the news media. Other rebel commanders have said that the U.S. bombing has driven Syrian fighters to join Nusra.
