Islamic State launches counter-attacks on U.S.-backed forces and Syrian army

The monitor said the ultra-hard line militants won back three villages south of the besieged city in a surprise assault against fighters from the U.S.-backed Syria Democratic Forces, in which at least 28 SDF fighters were killed.

Two years after IS proclaimed its caliphate to rule over all Muslims from swathes of territory in Iraq and Syria, its many foes are advancing on a number of fronts in both countries, with the aim of closing in on its two capitals, Raqqa in Syria and Mosul in Iraq.

The SDF were poised to enter Manbij nearly three weeks after the launch of a major assault to regain the city backed by U.S. air power and American special forces, to seal off the last stretch of the Syrian-Turkish frontier

U.S-led coalition jets hit militants taking cover near the large wheat silo complex on the southern edge of the city that has been encircled by SDF forces.

An SDF spokesman said they succeeded in repulsing the militant attack and remained positioned on the outskirts of the city, most of whose residents remain trapped inside and where the militants have planted mines and dug in to defend it.

“The situation is under control. They have many bodies on the ground,” Sharfan Darwish, spokesman for the Syria Democratic Forces-allied Manbij Military Council, told Reuters.

“We are at the four gates to the city. The whole city is booby-trapped. After 20 days of the campaign, we have yet to storm the city,” he added, adding that some 2,000 people had succeeded in fleeing the city.

Separately further south, Islamic State militants were also able to roll back the Syrian army which had got as close as 10 km south of the strategic town of Tabqa, an Islamic State-held city on the Euphrates River, in Raqqa province.

The town, some 50 km (30 miles) west of Raqqa city, the militant’s defacto capital, appears to be the first target of a major Syrian army assault in Raqqa province backed by Russian air power that began earlier this month. [L8N18W058].

Tabqa dam and a major air base have been in militant hands since 2014.

Amaq news agency, which is affiliated to the militants, said suicide bombers had attacked Thawra oil field, south of Tabqa, which the Syrian army had captured earlier this week and regained it.

Eyad al Hosain, a Syrian journalist embedded with Syrian troops, confirmed to Reuters the militants had succeeded in gaining back areas they lost near the oil field. He did not give figures on army casualties.

“A very intense attack has targeted army and allied positions in Thwara field that led to the withdrawal of troops from areas they liberated… and their retreat,” al Hosain said.

Amaq also said militants seized a Syrian army checkpoint near a strategic junction which leads to Raqqa city that the Syrian government forces and their allies had taken control in the early phase of its Raqqa campaign. [L8N1923VR]

The monitor, which tracks violence across the country, said the militants had sent reinforcements and cited at least three hundred fighters heading to Tabqa from Raqqa.
