US-backed Syrian forces said Sunday they have established a military council to push Islamic State group fighters out of their northern bastion of Al-Bab after ousting the jihadists from Manbij.

"We announce... the creation of the Al-Bab Military Council" tasked with driving IS from the town in Aleppo province, said the Syrian Democratic Forces alliance of Kurdish and Arab fighters in a statement, two days after driving the last jihadists from Manbij.
