"BEIRUT -- U.S.-backed fighters on Thursday closed all major roads leading to the northern Syrian town of Manbij, a stronghold of the Islamic State of Iraq and Syria (ISIS), and surrounded it from three sides, officials and Syrian opposition activists said.
The town is one of the largest areas held by ISIS in the northern Aleppo province. Many of its residents fled in advance of the upcoming battle.
Manbij is a waypoint on an ISIS supply line between the Turkish border and the extremist group's de facto capital, Raqqa. If the U.S.-backed Syria Democratic Forces capture Manbij, it will be the extremists' biggest defeat in Syria since government forces captured the central historic town of Palmyra in March."
Good news, imo.
