Syrian Kurds, on the Offensive, Push Deeper Into Islamic State Territory

Kurdish-led forces advanced on Monday deep into territory in Syria held by the Islamic State. This showing of new momentum comes after they unexpectedly seized a border crossing from the jihadists last week.
The Kurds, aided by U.S.-led air strikes and smaller Syrian rebel groups, had pushed to within 35 miles of the Islamic State's de facto capital Raqqa city.
The rapid advance into Raqqa province has defied expectations of a protracted battle between the Kurdish YPG group and Islamic State fighters, who waged a four-month battle for the border town of Kobani, where the Kurds finally defeated the jihadists in January.
