A delegation including senior US diplomat Brett McGurk met with members of a Kurd-Arab alliance fighting ISIS inside Syria on Saturday, Kurdish sources said Sunday.
The visit appeared to be the first by a senior US government official inside Syrian territory.
McGurk, who is US President Barack Obama's envoy to an international coalition fighting ISIS in Syria and Iraq, was accompanied by French and British officials, the sources told AFP.
One Kurdish source close to the meeting said a "high-level military delegation from the international coalition (against ISIS)," met Saturday with senior members of the Syrian Democratic Forces (SDF) alliance.
The source said the talks in the Kurdish town of Kobane covered "military plans" for the fight against ISIS.
