SURROUNDED: Syrian US-backed forces seize last route into Raqqa.

A spokesman for the U.S.-led coalition told The Associated Press that the Syrian Democratic Forces are now in control of all high-speed routes into Raqqa from the south. The Kurdish-led fighters had been advancing from the city’s east after they seized a major stronghold in May, and from the west and north.

“South of the Euphrates river the SDF now control all high-speed routes into Raqqa,” Col. Joe Scrocca, spokesman for the U.S-led coalition, said in emails to the AP. Moving toward the Euphrates from the east “would completely encircle the city and has been the SDF plan from the start.”

The Britain-based Syrian Observatory for Human Rights said a unit of the SDF has seized villages across the river, moving through the Kasret al-Faraj area. The Observatory described it as a “strategic” advance that completes the siege around Raqqa.

“IS has no other choice now but to surrender or fight to the end,” said the Observatory director, Rami Abdurrahman.

Perfect. U.S. Defense Secretary James Mattis has a plan to kill them all.
