Syrian fighters cut main road linking IS-held areas

US-backed Syrian fighters today cut the main road between the northern Syrian city of Raqqa, which is controlled by the Islamic State group, and the eastern city of Deir el-Zour, which is partially held by IS, as they press into the extremists' territory in Syria.
But despite the fresh blockade on the Raqqa-Deir el-Zour road, IS still controls large swaths of ground south of Raqqa and the extremists should be able to use smaller roads and paths through open desert to move between the cities.
Fighters from the US-backed and Kurdish-led Syria Democratic Forces have been on the offensive under the cover of US-led coalition airstrikes since November. Operation Euphrates Wrath aims to surround and capture Raqqa, the de facto capital of the IS self-declared caliphate.

The SDF began the third phase of Euphrates Wrath last month with the aim of capturing villages and towns east of Raqqa.
The Britain-based Syrian Observatory for Human Rights said SDF fighters cut the road linking the two cities in the area of Jazra near Raqqa early today. The group said it is now difficult for people to leave and enter Raqqa with the new territory captured east of the city and after last month's airstrikes by the coalition that destroyed two main bridges on the southern edge of Raqqa.
SDF spokesman Talal Sillo told The Associated Press that "our forces have cut the main supply line between Raqqa and Deir el-Zour." He added that it is still too early to impose a siege on Raqqa because the extremists still control areas west and south of the city.

SDF spokeswoman Cihan Sheikh Ehmed vowed that the campaign will continue "until Raqqa is totally isolated."

The blockade of the main road comes amid an ongoing SDF march toward Raqqa; its fighters are now stationed eight kilometres north of the Euphrates River city and supported by both coalition airstrikes and a deployment of some 500 US special forces operators.
The Pentagon has said its soldiers are working in a purely advisory capacity.
But Turkey, a US ally through NATO, views the Kurdish militia known as the YPG - the main component of the SDF - as an extension of the Kurdish insurgency inside its own borders and has classified the party as a terror organisation.

It has objected strongly to the SDF offensive and also vowed to repel the Kurdish-led forces in the town of Manbij back over the banks of the Euphrates, a move that would disrupt the Raqqa campaign.
