ISIL jihadists \'retreat from parts of north Syria\'

Jihadist militants train near the northern Syrian city of Aleppo The jihadist Islamic State of Iraq and the Levant has begun withdrawing from parts of northern Syria ahead of a deadline set by a rival group, a monitor said Thursday. The Syrian Observatory for Human Rights said the group was retreating east towards its stronghold in the city of Raqa.
The withdrawal comes four days after the Al-Qaeda affiliated Al-Nusra Front issued ISIL an ultimatum to go before an Islamic court for mediation or face being forced from Syria altogether.
The deadline expires on Saturday.
"ISIS has withdrawn from Aazaz, its most important bastion in Aleppo province, as well as the Minnigh military airport, the Mayer region and the villages of Deir Jamal and Kafin," the Observatory said.
"Aleppo region is their weakest link, so they fear being attacked there" by Al-Nusra and other rebels after the deadline expires, Observatory director Rami Abdel Rahman told AFP.
"ISIL is heading to areas that neighbour Raqa province where it has its main stronghold in the city of Raqa," he said.
ISIL fighters had regrouped in particular in Jarabulus and Manbij, on the far eastern border of Aleppo province and close to Raqa, he added.
Al-Nusra issued the threat against ISIL after the death of a senior Islamist commander, Abu Khaled al-Suri, who had close ties to Al-Qaeda chief Ayman al-Zawahiri and his predecessor Osama bin Laden.
Rival rebels accuse ISIL of killing the commander and Al-Nusra chief Abu Mohamed al-Jolani warned on Tuesday the group would be pushed out of Syria if it refused arbitration before an Islamic court.
Both Al-Nusra and ISIL have roots in Al-Qaeda's onetime Iraqi affiliate, the Islamic State of Iraq.
But the two groups have never merged, with Jolani rejecting a union proposed by ISIL and Al-Qaeda's Zawahiri urging ISIL to return to Iraq after they moved into Syria.
In early January, a coalition of Islamist and moderate rebels angered by ISIL's abuses of civilians and rival opposition fighters began attacking the group.
Al-Nusra initially remained out of the fray but in recent weeks has begun actively fighting ISIL.
