Syrian rebels seize swathes of south as Daesh retreats

AMMAN — Syrian rebels have seized large areas from the Daesh terror group in southern Syria in the last two weeks as the extremist group prepares to defend its Raqqa stronghold in the north from a US-backed assault, rebel commanders say.

The advances by Western-backed Free Syrian Army (FSA) factions have helped to reduce the risk of Daesh militants regrouping in areas near Damascus and the Jordanian border as they face major defeats in Syria and Iraq.

Western intelligence sources have worried for months that militants fleeing from their main urban strongholds of Raqqa in Syria and Mosul in Iraq could find a safe haven in the vast areas of the Syrian Desert bordering Jordan. 

Their sudden gains are a culmination of months of covert operations in which they have ambushed and cut communication lines to weaken the militants' stronghold in the southeastern border area close to Iraq, the rebels say.

"Extensive areas have fallen into our hands. [Daesh] has been pushed out of them in heavy clashes in 16 days of battles," said Talas Al Salameh, the commander of the Osoud Al Sharqiya, the biggest of the FSA groups in the area.

“[Daesh] had cut roads and were in control and had been positioned in former Syrian army bases with a strong presence and with heavy armour. We cut links between their areas and as a result they began to retreat,” Al Salamah said.

In northern Syria, Daesh has come under growing military pressure in recent months from separate campaigns being waged by the US-backed Arab and Kurdish fighters, by the Russian-backed Syrian army and by Turkey-backed FSA groups.

The US-led coalition against Daesh is backing an alliance of Kurdish and Arab fighters — the Syrian Democratic Forces (SDF) — in the campaign to isolate and capture Raqqa city on the other side of the country.

Troop movements

Salamah said Daesh had pulled hundreds of fighters from the areas where his group, working with four others, had made its advances, suggesting they had been redeployed to help defend Raqqa and Deir Ezzor province to the east. 

The advances have taken place in a swathe of sparsely populated territory stretching from the town of Bir Qassab, some 50km southeast of Damascus, all the way to the borders with Iraq and Jordan, a desert area known as the Badia.

“In the event of the fall of Raqqa and Mosul, where would they go? They would be coming here. So we decided to work and kick them out of this area before they would come to us,” Salameh told Reuters in a phone interview.

The rebels have also seized control of the eastern slopes of the Qalamoun mountains to the northwest of Bir Qassab, where Daesh’s presence had disappeared as it moved its forces further north, he said.

The rebels say their campaign in the area had been gradually escalated over the last five months.

Said Seif, an official in another FSA faction, the Shahid Ahmad Al Abdo group, said 250 sq.km had been captured in the Badia alone.

Salameh said at least 117 of his fighters had been killed in ferocious fighting over the last few months in what he said were relentless assaults and ambushes by the militants.

His group first fought Daesh when it took over parts of Deir Ezzor province at the height of its expansion in 2014. His fighters regrouped in areas near the Jordanian border, where their base was hit in a Russian air strike last year.
